Re: [Xerces2] How do we want Grammar Caching

I hope I'm not too late ...

In DTD, there is a rule that the first declared entity overrides other
declarations with the same name.  So if we try to cache one external
entity, you cannot do much parsing because any parameter entity can be
possibly overrided by the internal DTD subset.

So I think the minimum unit of DTD grammar is the whole DTD grammar.


Also, as related issue, I think it's very difficult to cache XML Schema
grammar at namespace-level. And why does this necessary after all? I
haven't seen such a use case before.
