Good sleuthing there... well done ... that points to interpretation of the 
stylesheet into a node tree.

Ahhh .. that points to a bug ... unless of course you used the MSXSL 
processor for your alternate test in which it isn't at all definitive 
because the Microsoft processor throws away whitespace-only text nodes 
contrary to the explicit specification rules[1].  If you used a processor 
conformant in the area of whitespace handling, then the test is more 
meaningful.

Do you have xml:space="preserve" used anywhere?  That overrides the rules 
regarding ignoring whitespace-only text nodes from the stylesheet node tree 
when building the result tree and would make any such annotated nodes visible.

I hope this helps.

whitespace-only text nodes, July 2003:

Microsoft's counter-claim:

My response:

Microsoft's position at the end of the debate:

  http://lists.xml.org/archives/xml-dev/200307/msg00885.html

I haven't heard anything official since, but as far as I know, this 
whitespace-handling behaviour has not changed.
