Yeah, well, the same goes for type annotations by schemas. Perhaps
XSLT 2.0 and XQuery will act as drivers for wide deployment of
Infoset annotations (I say with tongue in cheek).

Yes.

Yep, that would help. Also getting rid of the necessity to declare the
XLink namespace would help -- which would mean putting this stuff in
the 'xml' namespace -- the new attributes that Micah suggested,
stating that 'xlink' is a prefix that never has to be explicitly
declared (Namespaces 1.1 is still a WD; now would be the time to do
that), or having some new prefix (maybe 'xmllink') that can be
attached on any attribute to turn it into a link, as Eric suggested.

Cheers,

Jeni
