Just to pick up on a comment of Mark's from those minutes: [[ Mark: why would an author use anything other than id="A" and id="B" to refer to anonymous nodes?... why should I [as a document author] be worried about any outside use of those names? ... e.g. I use those names locally, but why should I prevent them from use outside? ... I think this is a concern more to RDF folk than to an HTML author. ]] I think the core distinction we need to get across, is between a worldwide, and hopefully well known identifier for something (a URI), versus a pragmatic, document-internal reference to something. drafting notes: """XHTML2's RDF-based metadata syntax allows document authors to describe properties of many kinds of thing, including relationships to real world objects that don't have widely known Web identifiers (URIs). Often a document might mention something (eg. a person, place, ...) without the author having a convenient URI that identifies it. This makes it difficult for different parts of a document to describe the same thing, without unnecessary repetition. XHTML2's metadata syntax provides a mechanism that allows different pieces of metadata within one document to clearly identify the things they're referring to, even without URIs: the @@@ and @@@ attributes are used alongside the "rel" attribute to link together pieces of meta information within an XHTML2 document. They function very similarly to the "about" and "href" attributes, but use identifiers which are strictly local to the document; this avoids any confusion between temporary or ad-hoc identifiers and those which are intended to be long-lasting, world wide identifiers (ie. URIs).""" Bit wordy and repetitative for the spec, but I think something like that needs saying... somewhere... Dan
