testsuite : principal-URL element vanished from lock answers

Hi,

I have run the functional test suite of slide.

I found that the people who created it did a great job.

The first issue which makes some test fail is that all the tests related
to locks expect a field principal-URL in the lock answer.
This field must have been removed sometime ?

So the result.xml contains this :

  <executeStep>
    <method>LOCK</method>
    <url>/slide/files/test/help-doc.html</url>
    <XMLSizeError>
      <path>/prop/lockdiscovery/activelock</path>
      <expectedSize>7</expectedSize>
      <receivedSize>6</receivedSize>
      <expectedElements>[depth, lockscope, locktoken, locktype, owner,
principal-URL, timeout]</expectedElements>
      <receivedElements>[depth, lockscope, locktoken, locktype, owner,
timeout]</receivedElements>
      <expectedAndNotReceived>[principal-URL]</expectedAndNotReceived>
    </XMLSizeError>
    <result>ERROR</result>
    <time>80</time>
  </executeStep>

Does anyone know who removed this principal-URL field, and why ?
Should this not be reinstated to preserve compatibility with previous
versions ?
Or should I amend the test suite so that it does not expect this field
any more ?

Regards,

Antoine
