I'm not sure we addressed those in the coding conventions.  I would like to say:

1) const references are always fine;
2) non-const references as local variables are always fine;
3) non-const references as function parameters should never be used
without a really excellent reason.

The reason is simply that using non-const references as function
parameters means that arguments passed to a function can change
without any indication, and that is potentially quite confusing.
Adding an & before an output argument is easy enough, and we're all
used to it.
