I don't think that it should mention validity at all. If authors want to make
sure their documents are valid there are plently of tools to do that without
consulting this polyglot spec.

It would be fruitless to try to enumerate the extra constraints one must
satisfy to ensure that a conforming html document that uses a legacy but
conforming doctype is valid xml.

@id being Name is a tiny fraction of it, also you'd have to not use any new
elements such as canvas, and the usage of all other elements would have to
match the dtd in addition to what the html(5) spec says. So long as the
document sticks to the single aim of specifying how to get conforming html
documents to have equivalent parse trees if parsed as XML, then xml validity is
irrelevant.
