Hi,
Modified 'SimpleTypeUsage' for the support added in DV implementation
for fundamental facet, shows how to get information about the different
fundamental facet 'ordered', 'numeric', 'bounded', 'cardinality' schema
components.-- regards, Neeraj Bajaj Sun Microsystems, inc. Phone: 080-2298989 x87425.
