Variations

The LANG, DIR and CHARSET attributes are introduced with the

internationalization proposal.

The CHARSET attribute is a hint as to the expected

character set used by the hyperlink.

Earlier proposals suggest changing the NAME attribute to ID,

declaring the NAME attribute as obsolete,

and adding an ID attribute for various elements

including the paragraph and heading elements.

With the ID, MD, and CLASS attributes as part of the style sheet

proposal, this is likely to change.

At present REV and REL are rarely used or supported,

and are Level 1 attributes,

but are of growing interest to automated document environments.

These relationships are more commonly identified in the

of the document using the element.

REL and REV can be either a comma-separated or white space separated

set of relationship(s) of the HREF link.

One proposal suggests that comma imply "or" and white

space imply "and" for a list of values.

These relationships and their semantics were originally proposed

to be registered with an HTML authority, which was described at

http://www.w3.org/hypertext/WWW/MarkUp/RegistrationAuthority.html,

but that link no longer responds. The entire topic of link relationships

is under active discussion and change.

Early examples of relationship names are

UseIndex, UseGlossary, Annotation, Reply, Embed,

Precedes, Subdocument, Present, Search, Supersedes, History, Made,

Owns, Approves, Supports, Refutes, Includes, Interested.

URN is for a Universal Resource Number, and is not currently

used or supported, and is a Level 1 attribute.

RFC 1866 describes it as a preferred, more persistent identifier

than the value of HREF.

TITLE is little used or supported, and is a Level 1 attribute,

but is expected to be the title of the HREF document.

RFC 1866 suggests TITLE can be displayed as a margin note
