And, adding to Mike's answer, the schema workgroup is devoting a lot of effort to choosing the right features for Schema 1.1 that would allow just such co-occurrence constraints to be expressed. Though I can't officially commit anything, I would expect to see at least some initial proposals in whatever is the next public working draft of the Schema 1.1 specification. Stay tuned. -------------------------------------- Noah Mendelsohn IBM Corporation One Rogers Street Cambridge, MA 02142 1-617-693-4036 -------------------------------------- "Michael Kay" <mike@saxonica.com> Sent by: xmlschema-dev-request@w3.org 05/12/2006 04:43 PM To: "'Crni Gorac'" <cgorac@gmail.com>, <xmlschema-dev@w3.org> cc: (bcc: Noah Mendelsohn/Cambridge/IBM) Subject: RE: specify element type depending of same element attribute value? > First problem is related to case > when type of contents of a simple element (not containing nested > element) is determined by this element attribute value. This is one of the most well-known restrictions in XML Schema. The type of an element is determined solely by its element name (and perhaps the context in which the element appears, and perhaps the xsi:type attribute). You can't write content models that depend on the presence or value of an attribute. Michael Kay http://www.saxonica.com/
