The HLink module defined in this specification provides XHTML Family Members with the ability to specify which attributes of elements represent Hyperlinks, and how those hyperlinks should be traversed, and extends XLink use to a wider class of languages than those restricted to the syntactic style allowed by XLink.
This section describes the status of this document at the time of its publication. Other documents may supersede this document. The latest status of this document series is maintained at the W3C.
This is the first Working Draft of this specification for review by W3C members and other interested parties. It is guaranteed to change; anyone implementing it should realize that we will not allow ourselves to be restricted by experimental implementations when deciding whether to change the specifications.

This section is informative.
This document defines markup that can be used to describe links in XHTML Family members. It consists of two elements that are used to associate properties with markup elements and attributes to describe how they behave as links. Many of the descriptive properties are taken from XLink [XLINK], but with additions to support the behaviour of links in XHTML.
This section is normative.
This specification defines a module called HLink. The module uses the XML
Namespaces [NAME] identifier
http://www.w3.org/2002/06/hlink.
Examples in this document that use the namespace prefix
"hlink" all assume an xmlns declaration
xmlns:hlink="http://www.w3.org/2002/06/hlink" somewhere suitable
in the document involved. All examples are informative.
The remainder of this section describes the elements and attributes in this module, the semantics, and provides an abstract module definition as required in [XHTMLMOD].
The HLink Module supports the following element and attributes:
| Element | Attributes | Minimal Content Model |
|---|---|---|
| hlinks | - | hlink+ |
| hlink | namespace* (URI), element (NAME), locator (CDATA), effect (CDATA), actuate (CDATA), replacement (CDATA), role (CDATA), reverseRole (CDATA), shape (CDATA), coords (CDATA), arcrole (CDATA), label (CDATA), from (CDATA), to (CDATA), mediaType (CDATA), onSuccess (CDATA), onFailure (CDATA) | EMPTY |
Implementations: DTD, RELAX NG, XML Schema
The hlinks element exists only to be a root element for a
document containing only hlink elements.
[[Issue: you could define inheritance in nested <hlink>
elements:
<hlink namespace="...">
<hlink element="a" ... />
<hlink element="b" ... />
</hlink>
This would make writing descriptions easier, and make an outer
<hlinks> unnecessary, though at the cost of complicating
implementation]]
Element hlink is used to identify an element and/or
attributes within a namespace, and associate properties with them to specify
how the element should be treated as a link, or how the attributes contribute
to an element that is a link. The hlink element has the
following attributes:
element attribute belongs to, or the
other attributes when the element attribute is
omitted.namespace. The rest of the
attributes below specify properties of this element. If this attribute
is absent, then the attributes describe global attributes (as defined
in [NAME]) within the namespace instead; these
attributes then describe the element that they are actually on in the
markup. If this attribute has the special value "*" then
the rest of the attributes describe all suitable elements in the
namespace (as defined by a DTD or schema)Each remaining attribute can be used in one of two ways: either it
specifies a value that indicates how the element is to behave as a
link-related element, or if the value of the attribute begins with the
character "@", it specifies the name of an attribute on the
element being defined that supplies the value. For instance:
locator="http://www.w3.org/"
says that the element in question is a locator for a fixed URI, namely
http://www.w3.org/. On the other hand
locator="@href"
says that the element in question has an attribute called
href, that contains the URI of the locator.
The remaining attributes are:
replacement attribute is located, and the resource
in that context is replaced by the resource identified by the
locator. If no such resource can be located, a new context with
that name is created, initialised with the identified resource.
If the replacement is absent (either directly by not
being present on the hlink element, or indirectly,
by being present but referring to an attribute on the described
element, that in its turn is not present), then the initiating
resource is replaced by the resource identified by the
locator.The default value is replace.
<a> element) may contain an image (for
instance using XHTML's <img/> element) that
itself has a descriptor to a link describing that image (such as
XHTML's longdesc attribute). The primary actuation
would activate the <a> element; therefore
there is a need for a secondary actuation method that allows
accessing other links accessible from that point.The default value is onRequest.
effect is present, with the value
replace. If effect is not present, or does
not have the value replace, this attribute has no
effect.This attribute gives information to the user agent about the role the link plays. [[More]]
[[These are the values that rel and rev can take according to HTML 4: Contents Glossary Copyright Chapter Section Subsection Appendix Help Bookmark Index Next Prev Alternate Start Stylesheet, and other specifications have added other values; e.g. P3P]]
effect of embed
and an actuate of onLoad. It has two values:
(If the element has no children, these two values are equivalent)
The default value is ignoreChildren.
effect of embed and an actuate
of onLoad cannot be actuated, either because of network
failure or the resource not being available or found, or because the
user agent cannot process the resource or the mediaType
attribute indicates that the user agent would not be able to process
the resource. It has four possible values:
The default value is warn.
[[Issue: onSuccess and onFailure need more work to cover other onLoad cases]]
[[Issue: markup for case where link has a side-effect]]
[[Issue: img map]]
[[Issue: form submit]]
<a href="..."> element in
XHTML:

In the context of this definition, and the namespace declaration

In the context of this definition and a suitable namespace declaration, the following markup will cause the initiating resource to be redirected:
<redirect href="whereever">This page has moved</redirect>
<html:blockquote>
<hlink namespace="http://www.w3.org/1999/xhtml"
element="blockquote"

This section is normative.
There are two ways to use HLink. The first is [[by
putting the <hlink>s in the <head>, and
the other by putting them in a separate resource, and referring to that
resource by a hlink:definition URI attribute on the root element
of the document
Either this
<html hlink:definition="http://www.example.org/whatever" ...>
or this:
<html ...>
<head>
<hlink:hlink ... />
...
</head>
]]
