Nested namespace changes get stripped in the result document

[GoogleCodeExporter]

When you have elements of different namespaces nested in an expect, ie:

            <detail xmlns="http://ns.electronichealth.net.au/ci/requirements/information">
                <div xmlns="http://ns.electronichealth.net.au/ci/requirements/information/xhtml2"><p style="text-align: left;">The document SHALL contain the individual's date of birth or approximated date of birth.</p><ol>
                    <li style="text-align: left;">one,</li>
                    <li style="text-align: left;">two,</li>
                    <li style="text-align: left;">three</li>
                </ol><br/></div>
            </detail>

If the namespace of the result doesn't match, XSPec will report them so, but it 
strips the namespace from the resulting output, showing the two results which 
are the same.

Result:
<detail xmlns="http://ns.electronichealth.net.au/ci/requirements/information"
         xmlns:pkg="http://expath.org/ns/pkg"
         xmlns:impl="urn:x-xspec:compile:xslt:impl"

      <br />
   </div>

Expecting:
<detail xmlns="http://ns.electronichealth.net.au/ci/requirements/information"
         xmlns:pkg="http://expath.org/ns/pkg"
         xmlns:impl="urn:x-xspec:compile:xslt:impl"

      <ol>
         <li style="text-align: left;">one,</li>
         <li style="text-align: left;">two,</li>
         <li style="text-align: left;">three</li>
      </ol>
      <br />
   </div>
</detail>

Notice how the namespace on the <div> is missing.
