[RIF-UCR] Proposed text for Rule language coverage

Hi,

In fulfillment of my action to send a proposal for the explicit statement of
the inter-dialect / intra-dialect interoperability, I propose to merge the
new "propose" requirement 5.2.5. with the existing general requirement
5.1.6. It is then clearly state the RIF MUST support intra-dialect
interoperability and SHOULD support inter-dialect interoperability between
different dialect whenever possible.

Here the proposed extended text for 5.1.6

5.1.6 Rule language coverage 

Because of the great diversity of rule languages, no one interchange
language is likely to be able to bridge between all. Instead, RIF provides
dialects which are each targeted at a cluster of similar rule languages.
Within that cluster, each feature of each rule language will have some
degree of commonality with corresponding features of other rule languages in
that cluster. The RIF dialect targeting a cluster must support, at a
minimum, interchange of rules using all the features which are common to all
the major rule languages in that cluster. That is, RIF must allow
intra-dialect interoperation, i.e. interoperability between semantically
similar rule languages (via interchange of RIF rules) within one dialect,
and it should support inter-dialect interoperation, i.e. interoperation
between dialects with maximum overlap.
