Namespace-aware XPath expressions?

Question

In xMII 11.5.2 b64, I need to extract a node from a SOAP message:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
   <soapenv:Header/>
   <soapenv:Body>
      <ns0:importRequest xmlns:ns0="http://www.acme.com/1.0/schemas">
        <FOO>
The following xMII Assign action Link returns me the entire <FOO> nodeset:
Transaction.SOAPRequest{/soapenv:Envelope/soapenv:Body/ns0:importRequest/*}
However, I cannot be guaranteed that the namespace prefixes will always be "soapenv" and "ns0".  For example, the following is perfectly valid:
<SOAP:Envelope xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/">
   <SOAP:Header/>
   <SOAP:Body>
      <ZZZ:importRequest xmlns:ZZZ="http://www.acme.com/1.0/schemas">
        <FOO>
When they are changed the XPath fails.  I have tried the following:
Transaction.SOAPRequest{/Envelope/Body/importRequest/*}
Transaction.SOAPRequest{//importRequest/*}
but they clearly don't work because the XPath evaluator in xMII is namespace aware (as it should be).
How can I declare namespaces in my XPath expression?  Or are there any other alternate ideas?
Thanks,

I installed SR3 and re-ran my tests and it still fails.  Here is my XML snippet:
<?xml version="1.0" encoding="UTF-8"?>
<SOAP:Envelope xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:sch="http://www.acme.com/4.3/schemas">
   <SOAP:Header/>
   <SOAP:Body>
      <sch:importIDOCRequest>
         <MATMAS03>
Here's the output from various expressions in the Link editor:
example 1 - getting the name of the root node:
"root node name=" & Transaction.SOAPRequest{name(/*)}
output 1 is predictable:
[INFO ]: root node name=SOAP:Envelope
example 2 - using 'senv' instead of 'SOAP' for the soap-envelope namespace prefix:
"importRequest child node name=" & Transaction.SOAPRequest{name(/senv:Envelope/senv:Body/sch:importIDOCRequest/*)}
output 2:
[INFO ]: importRequest child node name=
example 3 - no namespace prefixes specified:
"importRequest child node name=" & Transaction.SOAPRequest{name(/Envelope/Body/importIDOCRequest/*)}
output 3:
[INFO ]: importRequest child node name=
example 4 - using the same node namespaces prefixes as the input XML:
"importRequest child node name=" & Transaction.SOAPRequest{name(/SOAP:Envelope/SOAP:Body/sch:importIDOCRequest/*)}
output 4:
[INFO ]: importRequest child node name=MATMAS03
Any other ideas?
