Well, no need for an attribute, just turn your browser into debugging 
mode. Firefox, for example, would presumably report an invalid regexp to 
the JS console straight away, if a bug was filed requesting that. No need 
for the user to be exposed to it and no need for any special mode or 
attribute.
