(unknown charset) A problem on SAC 1.1

I'm Ho-sung Ahn.

I found a problem on a SAC interface.

The method getValue() in the interface AttributeCondition has a problem in
below case.

P.pastoral.marine { color: green }

The specification does not describe how implement the interface in above
case.

Should an implementation of SAC return "pastoral.marine"?

Thanks for your reading.
