Ah, OK, that's better.
It's not easy to grasp the correct terminology and structure from the
available documentation. I do appreciate the excellent help from the list
in such cases!
This part of the documentation might benefit from some examples of
generating different types of beamer syntax -- when to use properties, when
to use headline text, etc. I wouldn't have guessed to use the headline text
because I was thinking of parameters or arguments.

Under "Block environments and overlay specifications," where it discusses
custom environments, I would add:
~~
- Environment options may be given using the BEAMER_opt property. They will
be enclosed in square brackets and inserted where %o appears in the
environment definition.
(with an example, but I can't think of one now)
- Additional arguments may be written into the environment's headline, and
inserted into the LaTeX string using %r (raw headline text, no processing).
~~
I think it's important to mention it in the section where it can be used.
My faulty conclusion was based on the fact that the only mention of _opt is
in a section about frames.
