Permissable function arguments for the any-of-any function

[Steven Legg <steven.legg@enitiatives.com.au>]

The description of the any-of-any function in Appendix A.3.12 of
the Committee Specification 1 version of the XACMLv3 core specification
describes the first argument as naming "a Boolean function that takes
n arguments" in contrast to the other higher-order bag functions where
the first argument names "a Boolean function that takes n arguments of
primitive types". I assume that the omission of the "of primitive types"
in the description of the any-of-any function is just an editorial
oversight. If not, then there needs to be a better description of how
named functions that take bag arguments are to be applied by the
any-of-any function.
