xml-dev - XML Schemas: Needs Marketing?

["Roger L. Costello" <costello@mitre.org>]

Hi Folks,

[Case 1} The January 2000 issue of Application Development Trends has as
the title of its front page "Showtime for XML".  One of the articles in
this issue describes how General Motors has partnered with CommerceOne
to use XML in enabling Business-to-Business transactions.  It talks
about the limitations of DTDs and goes on to say that GM is using the
schema language that CommerceOne brings to the table, namely SOX.

[Case 2] Microsoft's Biztalk continues to grow and prosper.  It uses the
schema language XDR.

Questions: 
. Has XML Schemas already missed the window of opportunity to be the
schema language to supplant DTDs?  
. Is the world going to be fragmented with a bunch of different schema
language dialects?  
. Is fragmentation a bad thing or a good thing?  
. Perhaps the XML Schema WG needs to do some marketing?
