I glommed several different things together... I think each needs to be considered separately, although it may be OK to maintain them all under this one rule.
added code samples that i think illustrate the point and a reference to DCL07 since it deals with a very similar problem - alexv 5/15

As per Douglas's comment INT11-A. Do not make assumptions about the layout of bit-field structures has no business being in INT... should we move it to DCL?
