No.

[RIF cannot possibly model every possible conflict resolution strategy,
and indeed rule execution is orthogonal to rule representation and
interchange. So best leave alone, with the exception maybe of optionally
supporting rule priorities, maybe as metadata, to provide guidance to a
BRE].

On the topic of sequential/procedural interpretation of rules: it would
be nice to avoid precluding such a mode, but it is not a priority /
important for PRD version 1 IMHO.
