Following up on my own mail since this seems to be a problem with most <any>
elements in the Last Call Working Draft XForms schema - they require at
least one element to be present. According to the documentation for the
elements <schema>, <instance>, <caption>, <hint>, <help>, <alert> and
<value> they can all have empty content if a reference attribute is
specified. The schema should reflect this by using the minOccurs attribute
or many legal XForms documents will not validate correctly.

Verified this in Xerces and our internal validator, maybe XML Spy (which
apparently was used to author the XForms schema) has a bug regarding <any>
handling?
