Subject: RE: [xacml] IIC012: syntax-error or processing-error?

That's what we need function declaration syntax for..

The problem is - you may have a correct input type, but still get an error,
that has to be communicated in a generic way.  For example
account_balance(subject::account_id) may return INdeterminate for an invalid
account Id or for a failed query.  There is no easy way to validate that all
account_id used are valid before the evaluation - you would not want to
embed any cutom validation logic into your engine, would not you?

How do you handle the type-correctness checking in the case of
custom functions?  Do all custom functions have to be hardwired
into your XACML evaluation engine?  If not, and you have a
pluggable interface, is there some method to query for the types
of the arguments that a given function expects?  Or what?
