Yes really.

What is this "reuse these semantics" problem?  Once again, this is not
about what names could mean.

The notion that XSLT "needs" namespaces is the same delusion.

That is precisely what I mean by DWIMming: you are setting "rules" for
"others", not just for "yourself".

Yes, we know this.  That's how classical AFs work, for example (using a
validation schema to drive parsing).  But once again, I'm not concerned
with schema-driven parsing.  I'm concerned with markup to isolate that
which could be validated if someone wanted (but validation is *not*
necessarily the purpose of the discrimination achieved by parsing.)

Correct.  The spec is silent on this, and thus useless for the general
problem of vocabulary combination *by syntax*.

| You must also rely on the rule defined by your vocabulary.

Nope.  That's a myth too.
