Description:
------------
SoapServer response xml contains wrong references to node ids.

With PHP 5.2.3 we got this for returned items...
<item xsi:type="ns1:User" id="ref1">
  <sName xsi:type="xsd:string">userA</sName>
</item>
<item href="#ref1"/>
<item href="ref1"/> <-- See the missing '#' char
<item href="ref1"/> <-- See the missing '#' char

Manually changing the response xml to include the '#' solves the problem:
<item xsi:type="ns1:User" id="ref1">
  <sName xsi:type="xsd:string">userA</sName>
</item>
<item href="#ref1"/>
<item href="#ref1"/>
<item href="#ref1"/>


Reproduce code:
---------------
To reproduce this problem try to return the same object many times on any SOAP Service.
  
/** @return User[] */ 
function UserSoapService() {
  $aUser = new User();
  $aUser->sName = 'newUser';

  $aUsers = Array();
  $aUsers[] = $aUser;
  $aUsers[] = $aUser;
  $aUsers[] = $aUser;
  $aUsers[] = $aUser;
  return $aUsers;
}

/* Simple User definition */
Class User {
  /** @var string */
  public $sName;
}


Expected result:
----------------
Array with 4 times the same user object.

Actual result:
--------------
Exception of class SoapFault
SOAP-ERROR: Encoding: External reference 'ref1'
