[xacml] Reducing number of functions for 1.0

[Anne Anderson - Sun Microsystems <Anne.Anderson@Sun.COM>]

Are members interested in trying to minimize the number of functions
that have to be supported (and tested) for XACML 1.0?

Here are two proposals for reducing our current list:

1. Rather than support *-not-equal, expect people to use
   <function:not><function:*-equal>

2. Rather than support *-less-than and *-less-than-or-equal,
   expect people to use
        <function:not><function:*-greater-than-or-equal>
   for *-less-than, and
        <function:not><function:*-greater-than>
   for *-less-than-or-equal.
