No, they rely on user agents not checking for syntactically correct 
URIs. They aren't using URIs.

Oh well. Are you really believing this?

RFC2396 and RFC3986 define what a URI is. They do not and don't need to 
say anything about things which aren't URIs.

So, if at all, it would be the job of the HTML spec to say what to do 
with pages that use non-URIs where URIs are expected.

That being said -- James suggested "template" instead of "action" anyway.
