XML Schemas: Is it possible require an element contain *non-whitespace*

I'm looking into the use of schemas to validate form data submitted by
website users. Basically, when a user submits a form, such a system would
build an XML document from the data and then validate it using XML Schemas.

A common requirement with online forms is that the user has filled in
*something* into certain fields, i.e. they are mandatory. Is it possible,
with XML Schemas, to specify that an element *must* contain some text, and
that text must have atleast some non-whitespace characters in it?
