ISSUE-71 (External functions in Core): How can Core access external functions? [Core]

http://www.w3.org/2005/rules/wg/track/issues/71

Raised by: Dave Reynolds
On product: Core

DTB defines many operations that would be useful in CORE but defines them as functions rather than predicates and the current sketch of Core excludes equality and so has no easy way to obtain the results of such functions.

Options here would include:
(a) allow some syntactically restricted assignment-like use of equality in CORE to allow the results of external functions to be accessed;
(b) define predicate versions of those functions as part of CORE.
(c) define predicate versions of those functions in DTB.
