Re: 3.3 XML Analogue of HTML "<A"?

Yes, but that doesn't mean I go for reserved GIs, since (following
xml-link CDATA #fixed "xml-link" ?>
would do the trick.

As above, xml-link, with xml-mlink for non-inline-links.

See my comments on 3.2.b -- I like having the attributes on the
xml-link element itself, with similar names to the ones appearing on
each locator sub-element of xml-mlinks.
> 3.3.d Should we regard such an "A" link as involving one or two resources?
It must be two, surely, so applications can treat links and mlinks the
same for most purposes.

My draft proposal had a solution for that. As far as I can see the
only such metadata is not locator metadata at all, but resource (aka
endpoint) metadata, of which the only two proposed so far are role and
caption. I'd vote for using 'role' and 'caption' for the explicitly
located reference (i.e. the one specified using 'href' and 'hrtype'),
and using 'irole' and 'icaption' for the implicit resource (which
doesn't need 'href' or 'hrtype').
> 3.3.f SHould we provide a content model for "A" links?
No. Just as I can explicitly locate any sub-tree of a document, I
should be able to contain and implicitly locate any sub-tree, if I
write my DTD to allow it.
> 3.3.g Should we allow "A" links to contain anything other than PCDATA?
Yes, see above.
