I think they'd both have to be backwards compatible within the same ancestry, but maybe has added items not described in 3.3.

that's an interesting idea and maybe could provide scope for some minimal branching if required. The downside is it's not easy to express when branches are merged, e.g.


So i think 'version' should uniquely describe the version of the document within the namespace and something else should describe with which previous versions the interface is backwards compatible with.

Also my preference is to not restrict the contents of version or make it an 'integer'.
