Of course they do, so you need global rules for an ITS processor to
recognize them as such.
Enforcing is not just about testing. If someone introduces a global rule
using an extended element, it is against the spirit of the standard to let
this overlap with any ITS feature. If you do not use normative language to
say so in the spec, you have later on no base for saying that such use of
extensibility is not conformant...

I agree with the solution materially, all I say is that this must also
occur in prose descriptions of the elements.
