No. generateDS.py does not do anything to support xs:key and xs:keyref. I did a quick search on the Web and read just a little about them. But I admit that I don't know what generateDS.py should generate for those two (xs:key and xs:keyref) and for the xs:selector and xs:field elements that they contain. I found one document on the Web that said that xs:key and xs:keyref enforce a restriction (an integrity constraint) on the instance document. I believe that is what "XML Schema Part 0: Primer Second Edition" says, too. If that is all that xs:key and xs:keyref do, then perhaps generateDS.py does not need to do anything additional. Perhaps one way to satisfy your need is to send your XML instance documents through a tool that validates the document against a schema, for example xmllint. I don't know whether xmllint enforces that particular constraint, but perhaps one of the validators mentioned here does: http://en.wikipedia.org/wiki/XML_validation Is my understanding of xs:key and xs:keyref, as simple minded as it is, correct? Or, is there more in the way of support that you need. And, don't forget, Lxml does XML validation. So you could even build that validation into your Python code, whether or not you use data bindings (classes) generated with generateDS.py.
