Hello,

>>From the 1.0 spec:

"Substitution group
Any XML Schema concepts indicating that substitution group support is
a necessary component of the schema should be reported as an error."

When will Substitution group be supported?

Is my only alternative is to use a vendor extension to specify a common
supertype?

Thanks,
Gary
