i wouldn't have said it was included in the Cake core unless Nate or
someone else has come out and said so in the last 24 hrs.
if it is a successful method then I'm sure you could use it in your own helper.
i have written a html helper of my own that wraps around most of the
existing html helper functions as i just wanted a few changes and
tweaks here and there. e.g. image input function.
does this make sense?
