Yes, but:

  . please use TAG, not LABEL for the :label's argument, since that's
    what it is;
  . please say "evaluated", not "evalled"

I also question the wisdom of telling only in the doc string that the
tag is evaluated.  I could understand if you did that the other way
around, but if the doc string says that, the manual should also say
it.
