Subject: RE: low priority question about html:form
Quick note that the name, scope, and type attributes of <html:form> are
deprecated as of 1.1 and, AFAIK, have been removed in the current codebase.
So,
if there is a compelling use for them, it would be a good idea to address it
through Bugzilla ASAP.
