owl:sameAs confusion (Ref and Guide)

The HP team report that we have had difficulty working on owl:sameAs 
because different team members are working from different documents.

S&AS excludes owl:sameAs from OWL DL and OWL Lite.
Guide recommends not using owl:sameAs (ever), but states that it is 
synonomous with owl:sameIndividualAs, and suggests that using owl:sameAs 
between classes is in full.
Ref is more positive about owl:sameAs.

It would be helpful if the story were clearer, in particular Ref and Guide 
should say that all uses of owl:sameAs are in Full (personally, I would not 
mind simply dropping owl:sameAs).
