Re: Agenda item: XSD and DTD for CPP/CPA

[Martin W Sachs <mwsachs@us.ibm.com>]

Jamie,

I'm not sure that the problem you pose is relevant to the CPA.  In July,
2001, no one is likely to have a collection of legacy CPA DTDs that can't
be migrated.  I believe that at this time, the only question is whether the
would-be adopter is willing to spring for a Schema-based parser.  The fact
that the CPP and CPA use Schema doesn't affect the use of DTDs for business
documents.  The name of a DTD can be used as the document type.

Regards,
Marty

Just a preliminary reaction -- Isn't there a substantial non-behemoth user,
and would-be-adopter, base with a substantial legacy dependency DTDs?  You
might not want to bail on those people right away.    In spite of the
superiority and inevitability of schema, I'm not sure the upgrade path
looks easy to them.
