I would urge a degree of caution here.  It is _possible_ to do your
ontology at the same time you design your documents, but they _are_
two different things.  XML Schema is about documents.  UML is, I
presume, about ontology.  For small-scale and/or straightforward
projects, you can get away with doing domain analysis [= ontology] and
document design simultaneously, but only as long as you take careful
note when the constraints of the XML tree-structure-with-links data
model is in tension with the 'natural' domain ontology.
