XML : Difficulty with transform from SOAP response

From a SOAP response, I received the following XML:

  <?xml version="1.0" encoding="UTF-8"?>  <FindRelativesResponse xmlns="http://avid.com/interplay/ws/assets/types">    <Results>      <AssetDescription>        <InterplayURI>interplay://avideng103?mobid=060a2b340101010101010f0013-000000-53f2ae93b07200c3-060e2b347f7f-2a80</InterplayURI>        <Attributes>          <Attribute Name="MOB ID" Group="SYSTEM">060a2b340101010101010f0013-000000-53f2ae93b07200c3-060e2b347f7f-2a80</Attribute>          <Attribute Name="Moniker" Group="SYSTEM">1|F9E3A1A4-4CB9-45CC-A590-77A5D733B633|*|1121558|*</Attribute>        </Attributes>      </AssetDescription>      <AssetDescription>        <InterplayURI>interplay://avideng103?mobid=060a2b340101010101010f0013-000000-568ad56218ad42e7-060e2b347f7f-2a80</InterplayURI>        <Attributes>          <Attribute Name="MOB ID" Group="SYSTEM">060a2b340101010101010f0013-000000-568ad56218ad42e7-060e2b347f7f-2a80</Attribute>          <Attribute Name="Moniker" Group="SYSTEM">1|F9E3A1A4-4CB9-45CC-A590-77A5D733B633|*|4229098|*</Attribute>          <Attribute Name="CATDV RemoteID" Group="USER">11868</Attribute>          <Attribute Name="CATDV Animal" Group="USER">Tortoise</Attribute>          <Attribute Name="CATDV Director Approved" Group="USER">Director Approved</Attribute>          <Attribute Name="CATDV Location" Group="USER">Land</Attribute>          <Attribute Name="CATDV Time of Day" Group="USER">Day</Attribute>        </Attributes>      </AssetDescription>    </Results>  </FindRelativesResponse>    

However, my normal attempts at a transform on this are not working. I've tried the following:

  <?xml version="1.0" encoding="UTF-8"?>  <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"      xmlns:xs="http://www.w3.org/2001/XMLSchema"      exclude-result-prefixes="xs"      version="1.0">  <xsl:template match = "/">          <test>          <xsl:value-of select="FindRelativesResponse/Results/AssetDescription/Attributes/Attribute[@Name = 'CATDV RemoteID']"/>      </test>    </xsl:template>    </xsl:stylesheet>    

However, the result would be just empty in the test element.

I'm wondering if it has something to do with this: <FindRelativesResponse xmlns="http://avid.com/interplay/ws/assets/types"> I'm not used to seeing that so I'm wondering if there's a step I'm missing in the xslt.
