Subject: RE: [xacml] Notes for the call: Proposed Agenda, Sept. 19 Concal l...


It is possible I will have to miss the call.

I wanted to submit a vote on Funciton 0.9/0.11 additions
- I want to ask you to review my posts for the details.
I am opposed to the inclusion of "higher-order" functions into the spec
until the semantics of the function extension point is clarified.

1) There was no use case presented that requires such addition.  None.

2) While <Match> restrictions, as we discussed with Polar today, do solve
the issue with suitability of Match for indexing - it is not even needed, if
we do not specify the syntax that causes the need for this written
restrictions

3) Quting Polar: "Huh? From inside the extension function you can do what
ever you want. It's your ball game."   I very much disagree that we should
just drop the ball on trying to specify a useful portable semantics and
definitions for extensions.  Any language is as useful as its libraries.

4) If we decide to use "map" functions with return type specified by one of
its argument, we may just as well allow simple overloading of function names
based on the type of its argument. Then - specifying comparison operator to
be overloaded, in the same way, for bag arguments will eliminate the need
for the additions (if there was any).

While I understand that many do not care about this area - in my opnion it
is a deciding factor in XACML usability.

Regards,
Daniel
