Just a quick note when reading this post ... 
perhaps this is covered off in some digital 
signature specification.  I get a bit concerned when I read:

... because there is no "here()" function in 
XPath.  I cannot implement the above expression with a pure XPath processor.

The "here()" function cannot be an extension 
defined by any specification, because extension 
functions cannot be un-prefixed.

So I believe something must be changed in the 
expression ... regardless if the expression is mandatory or recommended.

I hope this helps.
