help/@appearance='minimal'

In the spirit of trigger/@appearance='minimal' I propose that
help/@appearance='minimal' offer the control label as a hyperlink which
provides the help on request.

XSLTForms implements this presently in conjunction with help/@href though
it need not be limited to that and ought to be able to work with text as
well.

See http://xformstest.org/klotz/2011/08/pizza/pizza.xml for an example.

In this case, the help hyperlink is traversed directly, but existing HTML
styling techniques can be used to turn it into a popup window, overlay, or
other style.

We've found this means of presenting help to be less visually confusing
than the common "help icon."
