FormEncode clearly crosses that line already -- there's lots of language
embedded in the validators.
That line generally is crossed in the message method, which is another
way you could handle this. An ad hoc solution here seems reasonable to me.

That's true.

You can use htmlfill to do a bit of this depending on whether there's
any error for a field (form:iferror), but yes, you can't do it based on
the particular error in the field.
