cc-cmt question about IT Environment SFRs in PPs and STs

[Tom Benkart <teb@coact.com>]

If a PP allocates SFRs to the IT Environment, is it permissible for STs to 
satisfy one or more of those requirements in the TOE and still claim 
conformance to the PP?

And (assuming it is), what is the appropriate way to specify those SFRs in 
the ST:

(A) Leave the SFRs in the IT Environment (essentially, do not claim that 
functionality in the TOE even though it is there)

(B) Move those SFRs to the TOE

If A, is it required that the TOE boundary be drawn such that the relevant 
functionality is outside the TOE boundary?  Do those SFRs have to be 
addressed by the evaluation evidence since it remains allocated to the IT 
Environment?

If B, do the corresponding IT Environment Objectives move to the TOE also 
(since TOE SFRs have to be mapped to TOE Objectives)?  What should be done 
if an assumption was mapped to such an Objective in the PP?  What happens 
if multiple IT Environment SFRs are mapped to one IT Environment Objective 
in the PP, and only some of those SFRs are satisfied by the TOE for a 
specific ST?

Thanks.

Tom
