Looks like I spoke too fast on this. I was assuming Elliotte meant that each RDDL document pointed to a schema for the entire document, but now realize he means that each RDDL document points to a namespace-specific schema that can be used to validate a document fragment. You then compose the validations of each fragment to determine validation of the whole document. With respect to Elliotte's last point (whether schema languages support this) I thought that XML Schemas did. -- Ron Ronald Bourret wrote: > > Elliotte Rusty Harold wrote: > > >I'm glad you write that.
