exclude-inline-prefixes question

I am not sure that the tests exclude-inline-prefixes #006 and #007 are
actually correct. For example, this is what the test #006 does:

<p:identity>
  <p:input port="source" xmlns:test="http://www.test.com">
    <p:inline exclude-inline-prefixes="test"><test:doc/></p:inline>
  </p:input>
</p:identity>

The test expects this to succeed, but because the namespace bound to
"test" is explicitly excluded, shouldn't the processor fail when it
encounters <test:doc/>?

If this is indeed the case and the processor should fail, what error
should it report? 

(Sorry if I just got confused.)
