  but again it makes very little sense as a namespace declaration is
just valid under the element subtree where it's declared, and it's
perfectly possible to have the same prefix bound to different
namespaces, not recommended but perfectly legal:

<foo:foo xmlns:foo="http://eample.com/foo";>
  <foo:foo xmlns:foo="http://eample.com/bar";>
    <foo:bar/>
  </foo:foo>
</foo:foo>

  So again basically doing that search is just a garantee that the
code it will be used for will break in weird ways when the input is not
as expected.

  In a nutshell Don't Do That !
