Tony you are correct, we did meet at XML 2005. Small world. :)
Thanks for the information. It is pretty much the same conclusion that
I've come to myself. I agree that long term specifications that
implement the standards can get a degree of interoperability and people
are not re-inventing the same wheel. I spent 10 years dealing with EDI
and the interoperability mess.
A follow up question, have you noticed anything in the way of
performance issues in regards to implementing CCTS? Particularly with
the additional namespaces a validating parser has to be aware. I've
done my own tests, and for both Xerces2 and Microsoft's validating
parser without pre-compiling the schema or doing parser pooling, it
seems to add about 71 milliseconds to the overall validation time.
This of course is greatly dependent on the size of the schema, and any
type of system over head.
