Hi Lisa, Since the schemaLocation attribute is only a hint, schema processors are allowed to ignore all but the first import for a given namespace. This is what Xerces-J does by default. To instruct the parser to read from all the schema locations specified for a given namespace you need to set the honour-all-schemaLocations [1] feature to true.
Thanks.
