schema : simpleTypeDecl : derivation : restriction

[Nick Betteridge <n....@syntactics.com>]

Hi

I'm busy working with xerces (head) for a schema editor and I've got an issue that I'm not too sure if it's a bug or not. The simpleType example I have is contained in the schema below. Take, for instance, simpleType "A". I can quite easily get the enumeration list with a xsSimpleTypeDecl.getLexicalEnumeration();. However, when looking at the xsSimpleTypeDecl.getFinal() to determine if there is a derivation, the result is always 0. Shouldn't this be XSConstants.DERIVATION_RESTRICTION?

Is this a bug or am I making a wrong assumption?

Very grateful for any input.

Thanks

Nick
