http://www.ietf.org/rfc/rfc1866.txt states:

  ACTION
             specifies the action URI for the form. The action URI of
             a form defaults to the base URI of the document


Also, from the DTD, we can see that form action is implied, and 
therefore need not be explicitly stated.

<![ %HTML.Forms [

<!ELEMENT FORM - - %body.content -(FORM) +(INPUT|SELECT|TEXTAREA)>
<!ATTLIST FORM
         ACTION CDATA #IMPLIED
         METHOD (%HTTP-Method) GET
         ENCTYPE %Content-Type; "application/x-www-form-urlencoded"
         %SDAPREF; "<Para>Form:</Para>"
         %SDASUFF; "<Para>Form End.</Para>"
         >

So, according to the spec, simply omitting the "action" attribute will 
do the right thing, as the document's base should be the URL of the view 
component.

However, this does not account for non-compliant implementations in 
browsers. But I'd rather have evidence of this non-compliance before 
putting in workarounds.
