Description:
------------
The XML returned has an Id node and an Id attribute. The parsed response creates 
an object and fills the Id value with the value of the Id attribute. De node's 
value is not used.

ID and IDREF attributes are predefined SOAP attributes and don't need to be 
parsed. Unfortunately .net soap services return the ID as z:Id, resulting in a 
parse.

Response XML:
<Person z:ID="i1" xmlns:z="http://schemas.microsoft.com/2003/10/Serialization/">
...
<Id>94acdd8b-2ae5-448a-9a61-d2df5218111e</Id>
...
</Person>

For me, preferred end result would be that we have the value of the node in Id 
and the value of the attribute in _Id or something like _attrib['Id'].

Expected result:
----------------
stdClass Object
(
    [Person] => stdClass Object
        (
...
            [Id] => 94acdd8b-2ae5-448a-9a61-d2df5218111e
...
        )
)

Actual result:
--------------
stdClass Object
(
    [Person] => stdClass Object
        (
...
            [Id] => i1
...
        )
)
