Mutually exclusive content type required

 WebDAV has a requirement that properties should be unique. In other words, they don't care what the element name is, as long as there is only one element with that name.  s4.5

This is an interesting case because it is the same requirement as that of IDs: that they are unique: the scope is perhaps different  (within an element versus within a document) but the requirement seems similar.

Can we have a restricted form of ANY to cope with this? Perhaps "ENUM" might be consistant.
