XACML 2

Hi,

I'm having some free time in the next weeks se I'll like to know if anybody have started with a 2.0 implementation. If so how do you manage the 1.1 and 2.0 differences and schema versioning issues (i.e. what happens if a 1.0 Context is evaluated using a 2.0 Policy, and issues like that).

Is there any document with all the differences between 1.1 and 2.0 wc-current? Because the differences are only available comparing the last version.

Thank you very much,
Diego Gonzalez
