Ok, so you're generating an XML tree in memory, filling in data, and
validating on the way out. Maybe this is of interest then:
Note that lxml does support XML Schema *validation*, it just doesn't care
about the schema while you are working on the tree, and it does not generate
Python code from it. It's dynamic, not static.
BTW, from the POV of objectify, generating Python classes from a schema would
basically mean infering a document instance from an XML Schema (sort of a
meta-model to model transformation). I find that an interesting relation, but
maybe that's just me...
