Comment #1 on issue 1024 by pekka.klarck: add tags or metadata to keywords
http://code.google.com/p/robotframework/issues/detail?id=1024
Something like this would be handy. Issue 925 already proposed similar
functionality and I resolve this as its duplicate. I commented that issue
and suggested that categories should be part of the documentation because
that requires less changes. On a second thought having explicit tags might
be a better idea, though.
Notice also that deprecating keywords is already supported:
