I don't like the word "conformant". The questions is, conformant to 
what? "Valid" at least is a little better defined with respect to HTML 
and XML.

Also, are we really sure that all document languages will have the rule 
that IDs do not repeat values? certainly that's a rule for valid HTML, 
XML, and SVG; but it's always struck me as a slightly funny one. Might 
there be a document language that does not have such a rule?

OK. That sounds reasonable. However I don't think it's totally obvious 
from the wording, so I would suggest adding a slightly redundant 
rephrasing such as, "If multiple elements share the same ID, then all 
are represented by an ID selector on that value." or something along 
those lines.
