Yes, that's what I had in mind.

I don't like mechanisms where the namespace depends on the context in which
an element appears. That seems likely to reintroduce many of the problems of
the current namespaces spec, where extracting a fragment of XML from the
middle of a document loses information that's needed to process it
correctly. Of course, my mechanism still has a context dependency (on the
"vocabulary definition"), but that's coarser grained and more likely to be
constant across an application, leading to a lower risk of data being moved
from one context into a different context that destroys its meaning.
