Thanks, it is much clearer with this example.
I try to guess where you'd run into a problem.

The <its:whatever> elements and one attribute
should work - the validator can still check
that the nesting is okay, and assume that the
<p its:translate="no"> is okay.

Here I'd expect it to report two erroneous 
attributes 'role' and 'aria-labelledby'.

Ditto the later 'property' and 'instanceof',
the validator cannot "know" what that is. (?)

For 'its:translate' it also doesn't "know"
what it is, but this obviously belongs to the
'xmlns:its' namespace introduced before.  

A hypothetical 'its:wiktionary' would trigger
no error, the validator simply ignores 'its:'

But it "knows" that 'aria-labelledby' is no 
attribute for <ul>.  You'd still get tons of
errors you're not really interested in... (?)
