The problem I have with that is that the Infoset isn't just describing a subset of XML syntax - it's creating an abstract representation of that syntax. To keep that abstraction from strangling the potential of the syntax, I'd much rather see the abstraction provide a full representation of the syntactic constructs _before_ subsetting it down to 'what comes out of the parser'. Too much gets lost in that transition, and leaving it entirely out of the Infoset will mean it's basically lost for good. Maybe it's time to strip XML down to the items listed in the Infoset, and discard everything else, but that seems like a more ambitious idea than the Infoset is supposed to be.
