I am not sure the Working Group really understood the issue, the
apparently complete examples do something like this:

  <?xml version='1.0'?>
  <element xpath='cdl:example(...)' />

How is the XPath engine supposed to know about the 'cdl' prefix?
What would happen for something like

  <?xml version='1.0'?>
  <element xmlns:cdl='... not cdl ...' xpath='cdl:example(...)' />

is this still a reference to a cdl function? What if

  <?xml version='1.0'?>
  <element xmlns:foo='http://www.w3.org/2004/12/ws-chor/cdl'
    xpath='foo:example(...)' />

is this a reference to a cdl function? None of this is currently
defined in the draft as far as I can tell. The prefix table is
fine, but the apparently complete examples in the draft are not
guranteed to work as advertized without clearer conformance re-
quirements. I think the XML Query / XSL Working Groups should
review the use of XPath in the document, I am happy to defer to
them on this issue.
