Following up. David was correct in that the .NET architecture was not
providing your typical nodeset to the 
XSLT. The System.Xml.XPath.XPathNodeIterator was essentially providing a
"windowPane" view of the original document 
through the $services parameter. Using the generate-id() showed
this.(Not explicitly mentioned on MSDN that I could find).

Changing preceding-sibling() to preceding() solved the problem.Thanks
for pointing me in the right direction on this one
David.
