[xacml] subjects

We have an open issue with subject designators that 
we want to solve asap.

There is a proposal from Polar, but I think it is 
too complicated for quick adoption.

 

My proposal:

a) Quick solution to vote on thrs: Keep current 
subject-attribute-designator element

with subject-category attribute and use it in 
the target and apply elements. Drop

subject-attr-desig-where. I think it will cover 95% 
of all cases.

 

b) Work out alternative proposal and delay voting 
until it is resolved
