Mark -- I'd like to reinforce your comment, below:

Multiple models will be a key issue when we start to explore XForms 
components in more detail.  The implementation I showed in Cannes in 
Eclipse, and the one we're completing now in Mozilla, both export an 
XForms model as the interface between each component and the enclosing 
form.  You can view this as an extension of John's argument about portals 
driving multiple models.  Portals are coarser-grained, but similar to 
components in that the final page rendered to the client depends on the 
interaction of multiple models whether at the root level (portal) or 
nested (components).

Thanks, Charlie
