Re: [xml] patch for w3c xml schema

["William M. Brack" <wbrack mmm com hk>]

Hi,

  I applied your patches (with a little minor 'cosmetic' editing)
for xmlschemas.c, as well as the 2 include files, and also changed
the test for po1_0.  That much is committed to CVS.  I'll go
through the additional test cases in the next couple of days, and
get them committed as soon as I can.

  Thanks very much for all of the effort you have put into this - it
will be greatly appreciated by many users!

Regards,

Bill
