Mike:
This is really a hard issue. There are problems with the W3C
schema specification. Every W3C situation I have encountered with my
clients who have contracted to have a W3C Schema created has issues. The
schema parses with the tool that was used to create the schema but does
not parse on any other schema parser. IMHO this is a very serious
situation. This means that the user is locked into a vendor specific
product. I don't believe this is because of vendor's diligence but
because of ambiguities in the specification.
Whether RelaxNG or W3C Schema's win is a wild guess. However,
if you compare the two, RelaxNG is less complex, more understandable
and easier to learn.
I believe RelaxNG is getting some 'wings' behind it because of
the OASIS-Open endorsement and the fact that it is going through ISO.
Timing is critical though, as we all know. The best solution doesn't
always win.
A lot of the organizations that I have seen that are busy
developing W3C Schemas are being sold a 'bill of goods' from
consultants and are not given a fair and balanced argument between
W3C, RelaxNG and DTD's.
Naturally these are just my opinions which you take with
a grain of salt |-).
