Documents structure and data models are, or should be, distinct.  XSD
is designed for use in defining the structure of XML documents.

Unless your data _is_ a set of documents, or naturally isomorphic to a
set of documents, starting out by trying to model it with XSD is
unlikely to be a good idea.

I would recommend modelling your data first, then looking at your
document requirements together with your data model to define your
document structure.
