General comments on parsers (was [NEW] AElfred)

[Matt Jones]

Thanks to the parser writers!

Like Peter, I am working on a project where we are building an XML
editing application in Java and therefore need access to the content
model for determining allowable content.  The msxml parser currently
doesn't make its internal representation of the DTD public -- Chris
Lovett suggested using the XML-Data Schemas instead of trying to access
the DTD info directly.  When one wants access to the DTD, what is the
recommended method?  Is there any concensus? Do any of the available
parsers (Lark, MSXML, NXP, PaxSyn, etc.)  plan on offering access to the
DTD through their APIs at some point?

Standardization of APIs (a la XAPI-J) would make life better as well --
are people working on this (Lark? MSXML? etc?)?

Thanks in advance,
Matt
