Thanks, I understand the purpose of FulfillOn from the documentation now (whether the obligation has to be fulfilled) so I will always set it to Permit for GUMS.
I assume the value of Status is application dependent since it doesn't specify the possible values. I plan on using values of ok and error (along with the stuff before i.e. urn:oasis:names:tc:xacml:1.0:status:).

This is complex. It would be nice if there was a wrapper function to only have to add the obligations and attributes and let the rest be default.

This is a type of function that you need to write, if you need it.

- If the user is not mapped, I set FulfillOn to 'Deny' and don't include an attribute assignment. Is this correct?
Comment: To deny authorization, we should use the Decision context.

Refer to the XACML specification. If it's not specified there then it is up to your application.

Questions:
What is the status context?

Refer to the XACML specification.

How is the FulfillOn attribute used in an obligation?

Refer to the XACML specification.
