Subject: Re: [xacml] CR 144: function "present" needs to be fixed.

If we adopt must-be-present it should have additional args:
must-be-present(attr-kind, attr-id, type-uri);

We also need similar function for the attribute-selector.
must-be-present-xpath(xpath-expr, type-uri)

We can not put functions in the target.

I'd prefer to have mustBePresent attribute in the attribute-designator
and attribute-selector elements. When it's value is set to 'true' and
attribute is not found, attribute-designator expression shall evaluate to
indeterminate.
