RE: Restricted element content

XSD 1.0 does not allow you to constrain the content of the text nodes in
mixed content.

It's worth bearing in mind that XSD was never designed to allow you to
describe arbitrary XML instance documents.  Rather it was designed to
support a particular set of widely used XML design patterns. Holding
structured data in mixed content elements is probably not a good idea; you
would be better off wrapping the positive integer in another child element.
This will be much easier to process in XSLT or XQuery.

With assertions in XSD 1.1, however, you can do what you like.
