object initialisation is not the only thing that HTCs provide. they also 
allow the provision of custom events. HTCs are the only way (that i know 
of) where you can fire custom events which will then be picked up by 
attached handlers. without this the "invalid" event would not be fully 
supportable, although you can still use directly assigned event handlers:
element.oninvalid = somefunction;

sorry for not answering this sooner i've been out of action for a week 
with a bug (the biological kind).
