Hmm.... I can add a comment in the javadocs of the SLDStyleFactory,
which is the piece of code that turns SLD trees into "resolved styles"
(that is, styles where theare are no more expressions, everything
is certain and evaluated). Do you know of a more appropriate place?
I would guess some where on our documentation of SLD and the examples pages.

Are you involved there? If not, what's the best way to ask for a
clarification?
I would certainly be able to do that, or TOPP could.
