Abstract

This note contains issues submitted against the XHTML 1.1 document that need to be addressed prior to updating it for Second Edition.

Status of this document

Since its release, a number of comments have been sent in against the XHTML 1.1 document. This document contains those issues, as well as a recommended disposition for each. Once the working group has confirmed the dispositions, a Disposition of Comments document will be created and made available to reviewers of the XHTML 1.1 Second Edition Proposed Edited Recommendation. This document summarizes the information about 21 open issues in the issue tracking system at http://htmlwg.mn.aptest.com/voyager-issues.

Note that the majority of this document is automatically generated from the Working Group's database of comments. As such, it may contain typographical or stylistic errors. If so, these are contained in the original submissions, and the HTML Working Group elected to not change these submissions.

This document is a Note of the W3C's HTML Working Group. This Note may be updated, replaced or rendered obsolete by other W3C documents at any time. It is inappropriate to use W3C Notes as reference material or to cite them as other than "work in progress". This document is work in progress and does not imply endorsement by the W3C membership.

This document has been produced by the W3C XHTML 2 Working Group as part of the HTML Activity. The goals of the XHTML 2 Working Group are discussed in the XHTML 2 Working Group charter.

Please send detailed comments on this document to www-html-editor@w3.org. We cannot guarantee a personal response, but we will try when it is appropriate. Public discussion on HTML features takes place on the mailing list www-html@w3.org.

614: XHTML 1.1 - http://www.w3.org/TR/xhtml-modularization/DTD/xhtml-special.ent None None N/A This is a comment against M12N, not against XHTML 1.1. It was fixed in M12N Second Edition.
8341: (X)HTML DTD <ul> stricly request <li> None None N/A This is a request to loosen the definition of UL and is a comment on M12N, not on XHTML 1.1. However, I believe we should reject the request because we never want to call a list with no entries valid.
656: Re: About disappearance of PE "Color.datatype" in XHTML 1.1 flat None None N/A This will be automatically addressed when the final flat version for Second Edition is generated.
8422: XHTML 1.1 Validation Problem None None N/A This is a lingering issue about whether an imagemap takes a URI or an IDREF. We have had many requests to change this. My recommendation is that we ask the HTML Working Group what *works* today in implementations and then support this in our languages. period. Even if doing so would make an existing VALID document INVALID. My rationale is actually spelled out by the requestor below. VALID and not working is useless.
472: Re: Errata in/comments on XHTML 1.1 None None N/A These have been fixed.
9716: XHTML 1.1 media types Modify and Accept None Substantive The working group agreed that the media type SHOULD be application/xhtml+xml. The group did NOT agree that we add the restriction about the document type text/html not being used because a document author may need to make that compromise. The working group does not believe the specification should prevent an author from making this compromise.
480: errata: XHTML 1.1 None None N/A I think we should re-introduce the name attribute for form and img. These attributes are needed by the (X)HTML DOM.
489: error in XHTML1.1 source None None N/A This is fixed.
478: http://www.w3.org/TR/xhtml11/xhtml11.html Reject None None This is an editorial issue with naming in XHTML Modularization. We can't change the names at this point.
469: Errata in XHTML 1.1 None None N/A These items have been corrected.
584: http://www.w3.org/TR/xhtml11/xhtml11.html Error Accept None Editorial Fixed.
6288: Error? in XHTML 1.1 Appendix B. Accept None Editorial Fixed so XMLNAMES is normative reference AND we are referencing second edition.
6933: XHTML 1.1 - Module-based XHTML [#2] Accept None Editorial Went through the document and ensured uppercase and annotations were used when an assertion was actually an assertion.
582: More error in XHTML 1.1 None None N/A Fixed editorial issue. Need to discuss whether @href on base is IMPLIED or REQUIRED for XHTML 1.0 and XHTML 1.1.
9609: XHTML 1.1 does not define media type None None N/A Fixed
650: Re: HELP: XHTML 1.1 and usemap's value None None N/A Looks like we resolved to change the datatype of usemap to URI sometime ago.
651: XHTML 1.1 with namespaces enabled? Accept None Editorial This was a comment. We changed the conformance language so it says the local part of the root element must be html.

  Hi,
  
  I've recently been validating a document that has an id attribute on a
  script tag. According to the XHTML 1.0 DTD, that seems to be valid.
  According to the XHTML 1.1 DTD, it does not seem to be valid. However,
  Appendix A in XHTML 1.1 does not list the removal of that id as a change
  from XHTML 1.0. Also, two of the four validators that I've tried (Page Valet
  and ARealValidator) claim that id isn't a valid attribute of script, anyway,
  regardless of the XHTML DTD used (I've e-mailed the authors of those,
  separately).
  
  The id for the script in the page I'm validating is going to be removed,
  because it's not very useful, but XHTML 1.1 would seem to be in error in
  removing that attribute, according to its own appendix.
  
  Or am I barking up the wrong tree?
  
  Regards,
  Grant Husbands.

  Dear HyperText Markup Language Working Group,
  
    It is not clear from the XHTML 1.1 Recommendations whether
  
    <form><div><form>...
  
  or
  
    <pre><span><ruby>...
  
  are allowed, since 
  
    <pre><ruby>...
  
  is not allowed it seems inconsistent to allow <pre><span><ruby>, for
  <form><div><form> this would be inconsistent with XHTML 1.0, please
  clarify this in the XHTML M12N SE WD and the XHTML 1.1 Errata.
  
  regards.

  Hi,
  
  IIRC the id attribute for the style element was added to XHTML 1.0 in its 
  Second Edition (2002-08-01). It, however, doesn't appear neither in XHTML 
  1.1 DTD nor in its Errata nor in Appendix A. "Changes from XHTML 1.0 
  Strict" (2001-05-31). Thus it's impossible to validly link from xml- 
  stylesheet PIs to internal styles. I think this should at least be added to 
  Errata.

  Subject: Change request of XHTML 1.1 DTD: use absolute URIs for Entities which are referenced from different base hrefs than the declaring document
  Date: Sat, 15 Sep 2001 17:50:32 +0200
  Message-ID: <000101c13dfe$26feb9e0$b18f9b3e@andromeda>
  
  Dear HTML Editors,
  
  I request a small change in the DTD for XHTML 1.1. The change would not
  change the structure or semantics, I only request to change a relative URI
  into an absolute one.
  
  When using XHTML 1.1 with current XML software, many parsers won't process
  the XHTML 1.1 but abort with an error message. The reason, of course,
  resides in errors in the parsers, not in the DTD files of XHTML 1.1 / XHTML
  Modularization.
  
  At least one parser, AElfred, which is used by the famous saxon XSLT
  processor, probably the most popular XSLT processor, has a serious bug.
  
  When using AElfred, I get the following error:
  > Transformation failed: java.io.FileNotFoundException:
  > http://www.w3.org/TR/xhtml-modularization/DTD/xhtml11-model-1.mod
  
  The reason is:
  http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd *declares* this Entity:
  <!ENTITY % xhtml-model.mod PUBLIC
  	"-//W3C//ENTITIES XHTML 1.1 Document Model 1.0//EN"
  	"xhtml11-model-1.mod"
  >
  (contains relative URI: xhtml11-model-1.mod)
  
  And http://www.w3.org/TR/xhtml-modularization/DTD/xhtml-framework-1.mod
  *references* this Entity:
  <!ENTITY % xhtml-model.module "INCLUDE" >
  <![%xhtml-model.module;[
  	<!-- instantiate the Document Model module declared in the DTD driver -->
  	%xhtml-model.mod;
  ]]>
  (changed formatting of both citations for readability)
  
  >From the XML Recommendation:
  "Unless otherwise provided by information outside the scope of
  this specification (e.g. a special XML element type defined by a particular
  DTD, or a processing instruction defined by a particular application
  specification),
  relative URIs are relative to the location of the resource within which the
  entity declaration occurs."
  
  Means *declaration*, not *reference*.
  
  But AElfred resolves the URI of the external parsed entity "xhtml-model.mod"
  at the *reference* the entity, not at the *declaration* of the entity.
  
  So this is what AElfred resolves:
  http://www.w3.org/TR/xhtml-modularization/DTD/xhtml11-model-1.mod
  And this is what conforming XML Parsers must resolve:
  http://www.w3.org/TR/xhtml11/DTD/xhtml11-model-1.mod
  
  So AElfred, at least the version used by saxon, has a bug.
  
  
  Since more XML Parsers and software based on them might have this bug,
  there's a hint on that on the www-html@w3.org mailing list, and since it
  will take some time until these bugs are fixed, I suggest, that the HTML
  working group changes the URI of the drivers to be absolute URLs.
  
  I suggest changing
  <!ENTITY % xhtml-model.mod PUBLIC
  	"-//W3C//ENTITIES XHTML 1.1 Document Model 1.0//EN"
  	"xhtml11-model-1.mod"
  >
  to
  <!ENTITY % xhtml-model.mod PUBLIC
  	"-//W3C//ENTITIES XHTML 1.1 Document Model 1.0//EN"
  	"http://www.w3.org/TR/xhtml11/DTD/xhtml11-model-1.mod"
  >
  in file http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd.
  
  I have *not* checked wether this is the only external parsed entity that
  requires a change of it's URI to work with buggy XML parsers.
  
  Nearly all other URIs already are absolute URLs, especially those
  referencing XHTML Modularization. I really do not think, that this change
  would have any side effects.

  Hi,
  
  I just want you to note that the DTD fragment 
  (ISO special entities for XHTML Modularization)
  contains two lines that may create broken XML if entity replacement 
  is applied on XHTML-1.1 documents:
  
  <!-- C0 Controls and Basic Latin -->
  <!ENTITY lt      "&#38;&#60;" ><!-- less-than sign, U+003C ISOnum -->
  <!ENTITY gt      "&#62;" ><!-- greater-than sign, U+003E ISOnum -->
  <!ENTITY amp     "&#38;&#38;" ><!-- ampersand, U+0026 ISOnum -->
  
  &lt; will be replaced by &< instead of &#60;
  &amp; will be replaced by && instead of &#38;
  
  Will this bug be fixed "in-place", or should I overwrite the corresponding
  entity in my DTDs with another version of the file?
  
  regards,
  jens

NOTES:

  This is a request to loosen the definition of UL and is a comment on M12N, not

  want to call a list with no entries valid.

  if you want to do a loop in a script set a class on the looped 
  attribute(s) and go that way, I see no point in loosening <ul> for a 
  "hey this might be possible"
  
  Plus, what would you say <ul></ul> (or more specific in XHTML <ul />) 
  would do...to me it would be a headache for any speach processor, and 
  just stuck there openly would be hard to STRUCTURELY accept.
  
  you need at least one list-item in a [unordered]-List, you can't really 
  call it a list without at least one item, can you (imho it should 
  restrict to at least two items, but thats just me).

  It seems the "flat" DTD used revision 4.0 of DTD modules, which was
  the latest version at the time XHTML 1.1 PR was published on 6 April 2001.
  REC version of DTD modules (published on 10 April 2001) were revision 4.1,
  and %Color.datatype; bug was fixed between these revisions, per PR#431 [1].
  We didn't regenerate the "flat" DTD when we published XHTML 1.1 REC,
  though, as Shane said, this doesn't really affect XHTML 1.1 per se.

  I tried to validate an document using the XHTML 1.1 DTD. I served it as application/xhtml+xml as I am supposed to do. However, I used a client-side image map in my document. It worked, but it did not validate. The validator said the "#" sign is not valid in the USEMAP attribute of the <img> tag, so I removed it. The image map didn't work after removing it, but it validated. I checked out your Image Module and your Client-Side Image Map Module. It seems that you guys forgot to add the USEMAP attribute to the Image Module. Is this true? Please reply.

  Which browser are you using?
  
  The usemap attribute is certainly in the Image Map module
  http://www.w3.org/TR/xhtml-modularization/abstract_modules.html#s_imapmodule
  and is clearly marked as an IDREF.

2.2 XHTML 1.1 media types

PROBLEM ID: 9716

STATE: Approved and Implemented
EDIT: Substantive
RESOLUTION: Modify and Accept
USER POSITION: None

NOTES:

  The working group agreed that the media type SHOULD be application/xhtml+xml. 
  The group did NOT agree that we add the restriction about the document type
  text/html not being used because a document author may need to make that
  compromise.  The working group does not believe the specification should prevent
  an author from making this compromise.

   From the new working draft of XHTML 1.1:
  
  > XHTML 1.1 documents SHOULD be labeled withthe Internet Media Type  
  > text/html as defined
  > in [RFC2854]
  
  Which says:
  
         In addition, [XHTML1] defines a profile of use
         of XHTML which is compatible with HTML 4.01 and
         which may also be labeled as text/html.
  
  ... making no mention of XHTML 1.1.
  
  > or application/xhtml+xml as definedin [RFC3236]. For further information  
  > on using

  > note [XHTMLMIME].
  
  Which says:
  
         In general, this media type is NOT suitable for
         XHTML.
  
  and
  
         The use of 'text/html' for XHTML SHOULD be limited
         for the purpose of rendering on existing HTML user
         agents, and SHOULD be limited to [XHTML1] documents
         which follow the HTML Compatibility Guidelines.
  
  and to paraphrase the summary tables:
  
         XHTML 1.1 SHOULD NOT be served as text/html
  
  Additionally, as far as I know, nothing added in XHTML 1.1 (i.e. Ruby  
  annotation) is supported by legacy user agents. So there seems little  
  point in allowing it to be served as text/html.
  
  I propose the following change:
  
  XHTML 1.1 documents SHOULD be labeled with the Internet Media Type  
  application/xhtml+xml as defined in [RFC3236]. They SHOULD NOT be labeled  
  with the Internet Media Type text/html as defined in [RFC2854]. For  
  further information on using media types with XHTML, see the informative  
  note [XHTMLMIME].

  At page

  it states that

  favor of the id attribute 
  	(as defined in [XHTMLMOD]). 
  
  I believe this should read "On the a, form, img, and map elements, . . ."
  
  Justification:
  
  (1) In the specification of XHTML 1.0, at page
  	http://www.w3.org/TR/xhtml1/
  it states (section 4.10) that
  	HTML 4 defined the name attribute for the elements a, applet, form,
  frame, iframe, img, and map. 
  	HTML 4 also introduced the id attribute. Both of these attributes
  are designed to be used 
  	as fragment identifiers.
  	. . . 
  	Note that in XHTML 1.0, the name attribute of these elements is
  formally deprecated, 
  	and will be removed in a subsequent version of XHTML.
  
  (2) XHTML 1.1 documents that DO use the name attribute with form or img
  elements do not validate with the W3C validator.

  You are right, XHTML 1.1 doesn't use the Name Identification Module [1]
  so the "name" attribute is not defined on "form" and "img", either.
  Thanks for your error report.

  Dear XHTML 1.1 editors,
  
  In the document XHTML 1.1 Recommendation [1]
  http://www.w3.org/TR/2001/REC-xhtml11-20010531
  
  We can read in the source code:
  ...................................................................
  <?xml version="1.0" encoding="UTF-8"?>
  <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" 
  "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
  <html xmlns="http://www.w3.org/1999/xhtml">
  <head>
  <meta name="generator" content="HTML Tidy, see www.w3.org" />
  <title>XHTML 1.1 - Module-based XHTML</title>
  <link rel="stylesheet" type="text/css" media="screen" href="xhtml.css" />
  <link rel="stylesheet" type="text/css" media="screen" 
  href="http://www.w3.org/StyleSheets/TR/W3C-REC" />
  <?xml-stylesheet href="xhtml.css" type="text/css" media="screen" ?>
  <?xml-stylesheet
  href="http://www.w3.org/StyleSheets/TR/W3C-REC" type="text/css" 
  media="screen" ?>
  <link rel="next" type="text/html" href="introduction.html" />
  ...................................................................
  
  
  But the Recommendation Associating stylesheets with XML documents [2] says:
  
  ........
  The xml-stylesheet processing instruction is allowed only in the 
  prolog of an XML document. The syntax of XML constrains where 
  processing instructions are allowed in the prolog; the xml-stylesheet 
  processing instruction is allowed anywhere in the prolog that meets 
  these constraints.
  ........
  
  So when the document is passed to the HTML validator [3], it is valid 
  against the XHTML 1.1 DTD but not against this Recommendation [2]. I 
  don't know if it's something the HTML Validator should check in the 
  future.
  
  Modularization of XHTML [4] seems to have the same problem.
  
  
  
  PS: Thanks to Max Froumentin, W3C, to have discovered the problem.

  Hi,
  
  Referring to http://www.w3.org/TR/2001/REC-xhtml11-20010531
  
  Section 3:
  
    there is an unmatched bracket in the second paragraph.
  
    the last module is introduced via "XHTML also uses the Ruby Annotation
    module as defined in [RUBY]". Since e.g. XHTML 1.0 doesn't use this
    module, it should the "XHTML 1.1 also ..." or "The XHTML 1.1 document
    type"
  
  Section 2.1.1:
  
    the last paragraph states (as in XHTML 1.0) about the XML declaration:
    "Such a declaration is required when the character encoding of the
     document is other than the default UTF-8 or UTF-16." 
  
    According to Philippe Le Hegaret this is wrong and subject for the XML
    1.0 SE errata. The sentence should be
  
    "Such a declaration is required when the character encoding of the
     document is other than the default UTF-8 or UTF-16 and no encoding 
     was determined by a higher-level protocol."
  
    I reported this to xml-editor@w3.org but got no reply till today.
    Maybe this should be discussed with the XML WG and corrected in
    XHTML 1.0 Second Edition.
  
  appendix b.1:
  
    Why has the normative reference to ISO 8879:1986 (SGML) been commented
    out?
  
  general:
  
    several passages use element tt where they should use code.

  This message is still in the incoming folder. I think this mainly is the
  case because most might think "this is just an s, what's the point?!".
  
  
  I explain.
  
  I am writing a documentation about HTML. This documentation shall document
  all elements and attributes of all official and unofficial HTML versions
  including their support in many browsers and their versions (at least 30).
  
  For newer, XHTML Modularization based, HTML versions, I wrote an XML
  document, which refers to the modules by their name. resulting document,
  which transforms the module selection document to a complete HTML version
  description by merging with module description documents, did not contain
  the expected table elements, because there was no module named "Table
  Module". It failed just because of that small missing "s".
  
  
  So sometimes, it's not a human, that works with a recommendation, sometimes
  its a machine. That's why I desire not just correct but identical spelling
  ;)
  
  
  And last but not least I want to thank the W3C for the great work and hope
  that XHTML Schemata will soon be available.

  Hi,
  
  In Appendix B of XHTML 1.1 [XHTML11], Namespace in XML [XMLNAMES]
  is described as an informative reference. But Modularization of XHTML
  [XHTMLMOD] is a normative reference of [XHTML11], and [XMLNAMES] is
  also a normative reference of [XHTMLMOD].
  
  i.e. 
  
  [XHTML11] +----------------- (informative) ---------------+--> [XMLNAMES]
            |                                               |
            +-- (normative) --> [XHTMLMOD] -- (normative) --+
  
  
  This is a little confused. Therefore, [XMLNAMES] as a reference of
  [XHTML11] should be changed to normative as well as of [XHTMLMOD].

  [ This was sent to www-html, but it is more appropriate to

  Hi,
  
  I would like to have a minor issue clarified.
  
  In "XHTML 1.1 - Module-based XHTML" (W3C REC 31 May 2001, 
  http://www.w3.org/TR/xhtml11/ ), in section 2, "Conformance 
  Definition",  (http://www.w3.org/TR/xhtml11/conformance.html) we find, 
  in the introduction, the following statement:
  
  <excerpt>
  The keywords "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", 
  "SHOULD", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to 
  be interpreted as described in [RFC2119].
  </excerpt>
  
  This wording  confused me, as I do not see any occurrences of uppercase 
  "MUST", etc. in the REC. Two possible interpretations:
  
  (1) "well, no harm putting this statement in the doc, event though it 
  does not apply to anything there."
  
  (2) "actually, this statement refers to _all_ occurrences of "must", 
  etc.,  in lower case as well as any other "cased" variants thereof."
  
  If the second alternative is the correct one, then one has to be very 
  careful when reading the REC. It of easy to regard "shall" as nice 
  syntactic sugar in the language, while "SHALL" definitely raises a 
  warning flag.
  
  I would be thankful for a clarification of how the excerpt reproduced 
  above applies to this REC.
  
  regards,

  Hello,
  
  In Section 3. The XHTML 1.1 Document Type,
  
  the module for the script element is named "Stylesheet Module". XHTML Modularization calls this module "Style Sheet Module".
  
  
  On the base element:
  
  In HTML 4.01, the href attribute of the base element is defined as #REQUIRED.
  In XHTML 1.0, the href attribute of the base element is defined as #IMPLIED.
  In XHTML 1.1, the href attribute of the base element is defined as #REQUIRED.
  
  I think, #IMPLIED is correct, because it should be able to use <base target="frame2" /> when the Frames Module is used.
  
  On the form element:
  
  The action attribute is required. I think it should be implied, and the user agent must use the URI containing the form element as destination for submitting the form when there is no action parameter.
  Anyway, action is a bad name for that attribute since it has similar semantics as href in a, base and link and src in img and ... (object, applet...). But I think this will change for the better in XHTML 2.0 when making use 
  of XML Base, XML Linking, XPointer etc..

  This is confusing, and what might be done to reduce the confusion is a 
  correction to the XHTML 1.1 specification, which is why I'm sending a 
  copy of this to maintainer of that document.
  
  In XML (as well as in SGML), when an attribute is declared to take IDREF 
  value, the value must be an identifier as such, without any # prefix, and 
  an identifier that is defined elsewhere in the document in an ID 
  attribute. More formally:
  
  "Validity constraint: IDREF
  
  Values of type IDREF must match the Name production, and values of type 
  IDREFS must match Names; each Name must match the value of an ID 
  attribute on some element in the XML document; i.e. IDREF values must 
  match the value of some ID attribute."
  
      http://www.w3.org/TR/2000/REC-xml-20001006#idref
  
  In XHTML 1.0, the usemap attribute in <img> is declared as %URI whereas 
  in XHTML 1.1 it is declared as IDREF. The same applies to some other 
  attributes as well, like usemap in <img>. I haven't studied the 
  differences systematically, but surely there are changes that should be 
  listed at
  http://www.w3.org/TR/xhtml11/changes.html#a_changes
  It is not sufficient to mention that "On the a and map elements, the name 
  attribute has been removed in favor of the id attribute". Related actual 
  changes elsewhere should be explicitly mentioned too. A clarifying 
  reference could be made to
  <http://www.w3.org/TR/2001/REC-xhtml-modularization-20010410/
  abstract_modules.html#s_imapmodule>
  
  This is a real change that makes some valid XHTML 1.0 documents invalid 
  under XHTML 1.1. In the other direction, things are different, since 
  usemap="foo" is valid in XHTML 1.0 but lacks useful meaning, since the 
  semantics is as defined in HTML 4.01:
  "usemap = uri [CT] 
  This attribute associates an image map with an element. The image map is 
  defined by a MAP element. The value of usemap must match the value of the 
  name attribute of the associated MAP element."
  <http://www.w3.org/TR/1999/REC-html401-19991224/struct/objects.html#
  adef-usemap>
  
  The semantic change should be noted too. XHTML specifications generally 
  make normative references to HTML specifications as regards to semantics, 
  and here the reference needs to be modified suitably.

  Greetings Jukka,
  
       The HTML Working Group recently discussed your email below. Thanks very
  much for your continued support and review of the HTML Recommendations. At
  our Group's most recent face-to-face meeting, this issue was discussed and
  the WG has acknowleged that this is indeed an error in the XHTML 1.1
  Recommendation, and we will rectify this error as soon as possible. The
  value of the usemap attribute should in fact be of type URI rather than of
  type IDREF. Thanks again for pointing this out.
  
  Regards,
  
  D-

2.13 XHTML 1.1 with namespaces enabled?

PROBLEM ID: 651

STATE: Approved and Implemented
EDIT: Editorial
RESOLUTION: Accept
USER POSITION: None

NOTES:

  This was a comment.  We changed the conformance language so it says the local
  part of the root element must be html.

  I've been wrestling for the last several hours over a conceptual 
  barrier.  I have a document which is valid XML, but technically is not 
  XHTML 1.1.  The doctype tag forces activation of the html: namespace 
  directly.
  
  <?xml version="1.0" encoding="iso-8859-1"?>
  <!DOCTYPE html:html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd" [
                 <!ENTITY % XHTML.prefixed "INCLUDE" >
                 <!ENTITY % XHTML.prefix "html" >
  ]>
  <html:html xmlns:html="http://www.w3.org/1999/xhtml">
  <html:head><html:title></html:title></html:head>
  <html:body>
  </html:body>
  </html:html>
  
  What bothers me is requirement 2 of XHTML 1.1, Section 2.1.1.  "The root 
  element of the document must be |<html>|."  
  
  My gut feeling says the above XML document should be treated as XHTML 
  1.1.  I'd appreciate some feedback on this.

  The root element is still <html>, you've just made the namespace explicit
  (normally it is defaulted). There's no problem.

  No, there is no suggestion that it is preferable. It is just an option,
  allowed by XML Namespaces. I was just pointing out that XHTML does not
  disallow it.
