Mike Cargal updated GROOVY-7874:
--------------------------------
Description:
The following code segment demonstrates parsing a schema and then serializing
with xmlUtil. xmlUtil, in it's attempt to discard necessary namespaces, is
discarding namespaces that are actually needed.
Save the original schema and the referenced schema in eclipse, and there will
be no errors. Save the output schema (as MyRevSchema.xsd for example) and
you'll have errors as a result of the dropped namespaces.
