I have parsed my XML file using the apache DOM parser and i am walking the tree. Now certain attributes are marked as Keys/keyrefs in the XSD file, while certain other attributes are IDs and IDREFs in the XSD file. While walking the tree i am able to correctly identify the ID and IDREF attributes by using attribute.getTypeName() and checking its either "ID" or "IDREF". What i also need to know is how i determine if an attribute is a key or a keyref? I am unable to find approprite methods to do so.




thanks in advance,
