I created the `[full-frame]` and `[cropped-sensor]` as described in [this question][1]. Both are widely used online and (at least in British) magazines and publications. Full frame is generally accepted to be 35mm equivalent, and I guess that many issues to do with the fact that a given D-SLR has a cropped-sensor will also apply to P&S cameras too. If it is D-SLR specific, then I would hope the question was also tagged `[dslr]` as well.

Certainly for Canon I feel it's important to seperate whether a question is to do with lens mounts or sensor size. Tagging with `[ef-s]` could relate to either, and also keeps Nikon users from the advice passed on, and we could end up with near-duplicates, with only the specific brands mentioned varying.
