I don't see any way to do it today, at least not directly.  You might
consider grouping each ActionError creation that needs this functionality
with setting of a form bean value which would be referenced from the "class"
attribute of a "label" or "div" element.  You could use that to control the
styling of the label.

There's some considering on the dev list about enhancing the "errors" tag to
get additional functionality to be able to iterate through the errors,
producing your own markup for each error.  I'm not very familiar with
javascript arcana, but is it possible for the emitted HTML to cause
execution of a javascript piece which could modify the document?
