ustiansky-1: What exception to raise? [link to this issue]

Some methods may raise several types of exceptions. It can be situations where more then one exceptional conditions are met at the same time. Is it described anywhere how to determine exceptions' precedence?

For example if I try to call insertBefore method on a readonly node with newChild being the node created from a different document, which exception should be raised: NO_MODIFICATION_ALLOWED_ERR or WRONG_DOCUMENT_ERR?

Error concerning
Node.insertBefore

aillon-1: Document.xmlVersion [link to this issue]

The draft states:

" An attribute specifying, as part of the XML declaration, the version number of this document. If there is no declaration, the value is "1.0". "

HTML (served as text/html) documents do not have XML declarations, and in this case it seems to me this propery should return null, not "1.0". Am I correct in making this assumption? Or should this really be returning "1.0" in that case as well?

Document interface, "xmlStandalone" and "xmlVersion" attributes: both descriptions say that there is a NOT_SUPPORTED_ERR if this document *does* support the "XML" feature. Shouldn't that be does *not* support?

the spec should clearly specify that when retrieving the value of an attribute that contains a reference to an entity for which no definition is available, the processor will treat this entity reference as an empty reference (see the reply to C15 in Core I18N response).

yergeau-3: Entity declarations [link to this issue]

The 4th paragraph starts "XML does not mandate that a non-validating XML processor read and process entity declarations made in the external subset or declared in external parameter entities." The last occurrence of "external" is superfluous and somewhat misleading, since non-validating processors are not obligated to read even *internal* parameter entities. This latter point is pretty obscure and under-documented in the XML spec, but see the last sentence in XML 1.0, as well as published erratum E8 at XML 1.0 Erratum E8.

lesch-1: isWhitespaceInElementContent or isWhiteSpaceInElementContent ? [link to this issue]

White space is two words (see all prose and productions in XML 1.0 except one typo in 1998 and the Infoset since WD-xml-infoset-20010202). I don't know why it wound up being one word in [element content whitespace]. Do you? isWhitespaceInElementContent could (should?) be isWhiteSpaceInElementContent and whitespace-in-element-content could be white-space-in-element-content. If Last Call is too late to change those, perhaps at least the prose could match XML and the Infoset to say "white space" (rather than "whitespaces").

Transition history

raised on 1 Aug 2003 by Susan Lesch
agreed on 14 Aug 2003

The name of the method isWhitespaceInElementContent has been changed to isElementContentWhitespace to better reflect that it refers to the Infoset property "element-content-whitespace". Same kind of change has been applied to the "whitespace-in-element-content" parameter. Since it is too late to rename the Infoset property, and our method and parameter are mapped to it, we don't plan to rename them, whatever the outcome of the whitespace vs white space is. Regarding the prose itself, we will happily change to whatever becomes the recommendation, and thus at any stage.

yergeau-4: redundant if? [link to this issue]

void Element.normalizeNamespaces()
{
      ...

      // Fixup element's namespace
      //
      if ( Element's namespaceURI != null )
      {
        ...
      }
      else
      {
        // Element has no namespace URI:
        if ( Element's localName is null )
        {
          ...
        }
        else
        {
          // Element has no namespace URI
          // Element has no pseudo-prefix
          if ( default Namespace in scope is "no namespace" )
          {
            ==> do nothing, we're fine as we stand
          }
          else
          {
            if ( there's a conflicting local default namespace declaration
                 already present )
            {
              ==> change its value to use this empty namespace.

            }
            else
            {
              ==> Set the default namespace to "no namespace" by creating or
              changing a local declaration attribute: xmlns="".

		}

There seems to be useless redundancy in the last "if". Paraphrasing: "If there's a declaration, change it, else create one or change an existing one". Either drop the "if" and keep the "else" part or keep the "if" and drop "or changing" from the "else" part.

yergeau-5: Namespace algorithm [link to this issue]

The first sentence (after the initial Note) is really hard to parse. Comments in the algorithms say things like "if the prefix/namespace pair is within scope...", using this wording would be clearer. It's not an element that's within scope, it's really the prefix/namespaceURI pair. Some rewording/tightening needed.

arnold-2: attribute name case [link to this issue]

" typically using uppercase for element names and lowercase for attribute names "

The "typical" behavior in the L3 Core is contrary to DOM L2 HTML which specifies that both attribute names and element names should be uppercase which currently only Opera and Konqueror implement. The best solution I see is to issue an errata to L2 HTML specifying that attribute should be lowercase. Otherwise, this sentence should be expanded to not appear to be recommending behavior contrary to L2 HTML.

The sentences:

"For instance, element and attribute names are exposed as all uppercase (for consistency) when used on an HTML document, regardless of the character case used in the markup. Since XHTML is based on XML, in XHTML everything is case sensitive, and element and attribute names must be lowercase in the markup. "

should read

"For instance, element names are exposed as all uppercase (for consistency) when used on an HTML document, regardless of the character case used in the markup. The names of attributes defined in HTML 4.01 are also exposed as all lowercase, regardless of the character case used in the markup, but for other attributes (i.e. ones that are not defined by HTML 4.01), the character casing is implementation dependent. Since XHTML is based on XML, in XHTML everything is case sensitive, and element and attribute names must be lowercase in the markup."

yergeau-6: actualEncoding vs xmlEncoding [link to this issue]

In C 1.1.1, Document.actualEncoding should be set to [character encoding scheme], which is "The name of the character encoding scheme in which the document entity is expressed." in the infoset spec, not necessarily the value of the encoding pseudo-att of the XML declaration. Document.xmlEncoding probably should not be set.

In appendix C.1.2, [character encoding scheme] should be set from Document.actualEncoding.

stenback-1: setting Document.prefix [link to this issue]

It appears that the DOM Core spec doesn't specify what should happen if the prefix attribute is set on a node of a type other than ELEMENT_NODE or ATTRIBUTE_NODE. It does state that the prefix is always null, but should setting it be a no-op or throw an exception?

arnold-5: getName vs getLocalName [link to this issue]

getName() does not define whether the return value is a local name or might contain a namespace prefix. I'd would assume that local name would be preferrable. Changing the name to getLocalName() would be clearer and consistent with XPath.

nichol-1: Node.namespaceURI [link to this issue]

Going back to DOM 2, this attribute's description has started "The namespace URI of this node, or null if it is unspecified". This seems quite clear, and in programming languages like Java, I expect a null value in that language to be returned.

However, there are implementations that do not use what I would consider to be a null. For example, Oracle's XML parser's Node.getNamespaceURI() returns an empty (zero-length) string, and Microsoft's .NET framework (the NamespaceURI property of the System.Xml.XmlNode class) likewise returns an empty string.

I would like to see DOM 3 Core clarify or amend the statement "The namespace URI of this node, or null if it is unspecified". If implementations returning empty strings are to be considered out-of-spec, please specify this explicitly. If returning a zero-length string is an acceptible implementation according to the standard, please state this. If this issue is clarified elsewhere in the DOM 3 spec, please refer to that place from the description of Node.namespaceURI.

manian-2: unspecified standalone [link to this issue]

To be consistent with the other attributes, probably it should be added that "This attribute is false when unspecified".

This is said to be from the XML declaration, but is boolean whereas the XML declaration can specify 3 values: "yes", "no" and not specified. Either the datatype should be changed or (my preference) it should be specified that this is true when the XML declaration says "yes", false otherwise.

Appendix C.1.1 says that this comes from the [standalone] property, but does not address the case where the property has no value.

arnold-18a: isWhitespaceInElementContent() or isWhitespaceInElementContent ? [link to this issue]

This would be more appropriate as an read-only attribute. The description is insufficient since it doesn't explicitly explain under what conditions the implementation is able and required to determine that the content model only contains elements.

done. For Java, if an attribute starts with "is" that is followed by an upper case character, then the getter keeps the name as-is. The setter replaces "is" with "set". Only exception is HTMLInputElement.isMap as suggested. IsId and isWhitespaceInElementContent (now renamed to isElementContentWhitespace) are back to be attributes again.

We renamed the method to make it clear that it reflects the Infoset property "elenment-content-whitespace". Also added a link to the Infoset in the description.

arnold-16: Position comparison [link to this issue]

How do the definitions differ from XPath's axes? Why CONTAINED_BY instead of ANCESTOR and CONTAINS instead of DESCENDANT? Could there not be bits to indicate parent, child, attribute, sibling and self? Is there a compelling reason to fabricate an order for attributes of the same element or for nodes in different documents?

I would think that Node.compareDocumentPosition would be very prone to usage errors. Most scripting languages would not provide symbolic constants and it would be relatively easy to misuse bit-wise operators.

It would seem a whole lot simplier and more usable to provide boolean methods that correspond to the XPath Axes,

boolean isChild(Node node);
boolean isDescendant(Node node);
boolean isParent(Node node);
boolean isAncestor(Node node);
boolean isFollowingSibling(Node node); // always false for attribute
boolean isPrecedingSibling(Node node);  // always false for attributes
boolean isSibling(Node node);
boolean isFollowing(Node node);
boolean isPreceding(Node node);
boolean isAttribute(Node node);

Plus the existing isSame(Node node) for the self axis. descendant-or-self and ancestor-or-self could be handled by or'ing isSame and the appropriate other axis test.

Adding a method to determine if the nodes are in the same document might also be helpful.

If you are only interested if the particular pair are, for example, parent and child, it should be more efficient to only check that instead of figuring out how they are related.

Node.compareDocumentPosition

Transition history

raised on 31 Jul 2003 by Curt Arnold
declined on 14 Aug 2003

The addition of several methods in order to achieve the current functionality of compareDocumentPosition doesn't really encourage to change the current proposal, especially since it is easier to add a new constant than a new method if future extensions. So we still prefer the current proposal in the specification...

adler-1: "negative count" and unsigned counts [link to this issue]

Consider the interface CharacterData from DOM Level 1. The method deleteData has an unsigned long parameter named count. The technical report says that if the specified count is negative the exception INDEX_SIZE_ERR should be raised. But since count is an unsigned long, it makes no sense to say an exception should be raised if the count is negative; an unsigned long can't be negative.

In practice, this creates a problem for language binding implementors. For example, the W3C DOM test suite has an ECMAScript test that attempts to pass a negative number to deleteData, and expects INDEX_SIZE_ERR. But conceptually, it's the ECMAScript DOM language binding that is going to encounter the need to convert the negative number to an unsigned long, and I think it may be unreasonable to expect the language binding to know that it should raise a DOMException INDEX_SIZE_ERR in this case, since the process of converting argument types shouldn't be required to know details of individual DOM methods.

I was unable to find any standard that defines what should happen to values of inappropriate types that are passed through a language binding. I expect that's outside the scope of the DOM technical report.

There's definitely a problem here, but I'm not sure what can be done to the DOM technical report to fix this. Perhaps the idea of using unsigned long as the type in the CharacterData interface is the problem; it's certainly inconsistent to talk about a negative count if a count is an unsigned long.

This issue exists for the substringData, insertData, deleteData, and replaceData methods of the interface CharacterData, and the splitText method of the interface Text.

arnold-18: isId() or isId ? [link to this issue]

Attr.isId() is a declared as a method, though it would be more appropriate as an attribute. If made a read-write attribute, then Element.setIdAttribute(), Element.setIdAttributeNS() and Element.setAttributeNode() could be eliminated since you could do the equivalent using Element.getAttributeNode[NS]().isId = true | false.

Proposal concerning
Attr.isId

Transition history

raised on 1 Aug 2003 by Curt Arnold

    Characters are fully-normalized according to the rules defined in [CharModel] supplemented by the definitions of relevant constructs from Section 2.13 of [XML 1.1], if the normalization happened at load time, or by calling the method Document.normalizeDocument() (in both cases, the parameter "normalize-characters" needs to be true).

yergeau-14: normalize() and character normalization [link to this issue]

This should also perform character normalization, perhaps conditional to the config of the containing Document. This method's business in life is to concatenate Text nodes; concatenation is one of the well-known cases that actually produces character denormalization. It would be silly to have a method called normalize() which actually denormalizes, so any denormalizations caused by concatenation should be repaired as part of the method's normal functioning. Backward compatibility can probably be addressed by making the repairs conditional on xmlVersion or the config of the containing document or both.

Also, it should be specified that this method is sensitive to the value of the "cdata-sections" config parameter.

normalize() is a DOM Level 1 method. The name is unfortunate since it collides character normalization but we cannot change its semantics or rename it. This explains the introduction of normalizeDocument(), instead of reusing normalize() on Document nodes. An other example of discrepancy with names is our namespaceURI and the [namespace name] Infoset property.

This doesn't seem to address the comment. Backward compatibility is certainly an issue, but not necessarily a show-stopper: there are numerous instances of "Modified in DOM Level 3" in the spec.

yergeau-12: actualEncoding and xmlEncoding [link to this issue]

This is very much improved since the previous version, but unfortunately still not totally clear. Since the DOM stores documents in UTF-16 exclusively, these attributes must necessarily refer to the encoding of a serialized document that is parsed to create the DOM tree; since xmlEncoding is not read-only, it can also be set programmatically, but that shouldn't change its semantics. Semantics is precisely where some dark spots remain. actualEncoding is pretty clearly defined as the actual encoding of the parsed document, supposedly gleaned from the parser. xmlEncoding is then said to be taken from the XML declaration, but Appendix C.1.1 says that xmlEncoding is supposed to come from the infoset's [character encoding scheme] property. The latter is defined as "The name of the character encoding scheme in which the document entity is expressed", matching the semantics of actualEncoding, not those of an encoding label read from the XML declaration. So the meaning of xmlEncoding remains pretty murky.

One wonders why there are actually 2 attributes, since there is only one encoding of interest: that of the document that was parsed to create the DOM tree. If the intent was to enable DOM users to control encoding during later serialization, this is defeated by the order of priorities specified in DOMSerializer.write(): actualEncoding precedes xmlEncoding. The former being read-only, the user has no control.

Clarification concerning

Transition history

raised on 8 Aug 2003 by François Yergeau, on behalf of Internationalization WG

xmlEncoding is now read-only, and only represents what was found in the XML declaration, if any. actualEncoding was the encoding used to load the document, again if any. For the Save module, it should be clarified that the XML declaration, if generated, will get whatever encoding was used for the serialization, and not actualEncoding or xmlEncoding necessarily.

adams-1: DOMImplementationRegistry behavior [link to this issue]

The implementation of DOMImplementationRegistry shown in Appendix G.1 makes use of a Java System Property to record a list of names of classes that implement DOMImplementationSource. A user of the registry may naturally infer that sources are checked in the order specified by this property (and the order by which additional sources are added to the registry using the addSource() method). However, this may or may not be the case since the implementation of DOMImplementationRegistry shown here makes use of a Hashtable which does not guarantee any specific enumeration order.

I would suggest doing one of the following:

  1. abstract the definition of DOMImplementationRegistry in Appendix G.1 to specify it in terms of an interface rather than a class; furthermore, define its behavior more clearly in terms of order of evaluation in the case that two or more DOMImplementationSource instances implement the same features;
  2. rewrite the implementation in G.1 to use an ordered container type, such as a List;
  3. specify that the behavior is undefined as to which DOMImplementationSource will be returned when more than one supports the same features.

Not common enough as a use case to be addressed by the API. This can be done easily by the application anyway.

arnold-20: User data and event handling [link to this issue]

I would prefer enhancing Events to enable UserData maintenance, though that may require defining events types for cloning and importing and adding a DOMStringList userDataKeys attribute to Node.

If not, does there need to be an NODE_ADOPTED operation type.

NODE_DELETED is problematic. However, mimicing DOMNodeRemovedFromDocument would be well defined for garbage-collected platforms.

it would also require to support events in order to handle the user data appropriately. NODE_ADOPTED has been added instead.

arnold-21: anonymous types [link to this issue]

Having attributes that allow you to readily determine if the type is complex vs simple or named vs anonymous would seem to be helpful. Such as:

readonly attribute boolean isSimple;
readonly attribute boolean isAnonymous;
      (may be redundant with typeName == null)

This request goes into the debate of how much of the PSVI API should be included on this interface. We judge this one to be a real PSVI addition than a type generic one.

yergeau-16: "cdata-sections" default must be false [link to this issue]

This should default to false. CDATA sections are mere syntactic sugar with no structural role (hint: they do not exist in the infoset), they do not deserve to be preserved by default.

parameter "cdata-sections"

The parse methods of the LS module don't load CDATA sections by default (the "infoset" parameter is true by default, this implies that cdata-sections default is false for the parse methods). So unless an application adds CDATASection nodes during manipulations, the "cdata-sections" parameter won't change anything in the tree. And if the application do add CDATASection nodes in the tree, or the parse operation was requested to preserve the cdata sections, then they should be preserved by default since the application explicitly asked to get them.

arnold-13: adoptNode and importNode [link to this issue]

The difference between adoptNode and importNode is not immediately obvious.

Editorial concerning

We think that the current description is clear enough.

Acknowledgment cycle

proposal from reviewer on 29 Aug 2003

It would be good if the first sentences in each description were parallel. For example, adopt could say:

"Attempts to adopt a node from another document to this document. [...] If supported, the source node is removed from the original document and altered changing the ownerDocument of the node and any descendants,,,"

proposal incorporated by group on 29 Aug 2003

The new text says:

"Attempts to adopt a node from another document to this document. If supported, it changes the ownerDocument of the source node, its children, as well as the attached attribute nodes if there are any. If the source node has a parent it is first removed from the child list of its parent. This effectively allows moving a subtree from one document to another (unlike importNode() which create a copy of the source node instead of moving it). When it fails, applications should use Document.importNode() instead."

yergeau-17: check character normalization? [link to this issue]

it is not clear *when* this setting has any effect (i.e. what methods of what interfaces it affects). Since Charmodel says that text SHOULD be checked, the default for this should be true, the user having the chance to set it to false after careful consideration of the consequences (see definition of SHOULD in RFC2119).

Clarification concerning
parameter "check-character-normalization"

Transition history

raised on 8 Aug 2003 by François Yergeau, on behalf of Internationalization WG
declined on 14 Aug 2003

The parameter check-character-normalization is optional so the default cannot be true. Applications can certainly check if the parameter is activated, or can be activated, using the methods defined on the DOMConfiguration object.

objection from reviewer on 23 Sep 2003

The optional character of check-character-normalization is the first wrong (the other being that "true" is not the default). As argued in our comment, a DOM user cannot do the right thing (check normalization unless careful consideration of the consequences...) if the normalization checking functionality is absent. The DOM is missing functionality essential for things as ssimple and basic as string matching. We object to that.

objection maintained by group on 2 Oct 2003

For performance reasons, we believe the character normalization cannot be true by default. Also, no one in the WG committed to implement this feature.

arnold-12: Requirements of standalone [link to this issue]

What occurs when this attribute is set to true and the document does not satisify the requirements for standalone="yes".

Proposal concerning
Document.xmlStandalone

Transition history

raised on 30 Jul 2003 by Curt Arnold
agreed on 14 Aug 2003

normalizeDocument and the DOMSerializer will catch it, as defined by the XML specification: this is a validity constraint. I added for that effect in the description of xmlStandalone.

Acknowledgment cycle
announced by group on 28 Aug 2003
proposal from reviewer on 30 Aug 2003

There should be something in L/S that allows you to specify that you want to document serialized with standalone="yes" which would either place everything in the internal subset or expand entity references and explicitly serialize default attribute values.

declined on 8 Oct 2003

It would be dangerous to start doing "magic" based on the value of thestandalone attribute. XML Parsers are required to check the value ofstandalone when validating. It is therefore logic to do the same in theDOM and make the check dependent on the validate and validate-if-schemaparameters. No change is needed in the specifications since this errortype is already controlled by XML.
