I changed the first sentence to read:

  A p:xpath-context element specifies the context node against which...
                                                  ^^^^

And added the following paragraph:

  <para>The <tag>p:xpath-context</tag> element only provides the
  context node. The namespace bindings, in-scope variables, and other
  aspects of the context come from the element on which the XPath
  expression occurs.</para>

                                        Be seeing you,
                                          norm
