Re: disallow distributed switch branches

On the conf call yesterday, we had the impression that
the LRM prohibits OOMR contributions to switch branches,
but we were having trouble tracking it down.

In LRM 2.2, section 5.3.1.3 Value retention, I found this:
"It is illegal to contribute to an external switch branch
from within an analog block."

What's not explicitly said is that it would be illegal
to make an external branch a switch branch by means of
a contribution from within an analog block.  Eg, a
module has I(br) <+ 5; and then a second module tries
to set V(A.br) <+ 0;  This would have the effect of
converting br into a switch branch, and then the
contribution would be illegal, I believe.
