XACML 3.0 core wd 7

[Erik Rissanen <erik@axiomatics.com>]

All,

I just posted WD 7 of 3.0 core. See the changelog for changes. There are 
lots of small changes in there.

Before going CD, there is one more open issue to fix:

- Decide on how we want the combining algorithm logic to be (biased vs 
non-biased variants?)

Best regards,
Erik
