<AnyElements>

to the best of my knowledge, no one is actually performing evaluations 
directly against an XML document. so as i see it, unless someone can 
make the case that Any* actually creates ambiguity 


Mandatory <Any> DOES create ambiguity in one case I am working with.

There is NO concept of separate Action and Resource.  What does
<AnyAction> mean if there is NO Action?

The only real reason to separate <Rule> into Condition and Target
elements is efficiency.  Using the Target structure to impose particular
structure on the context (separating it into
Subject/Action/Resource/Everything fixed subspaces/scopes) is not a very
good idea IMO.
