I think I'd prefer to see some generic name for a 425 like error code eg.
(Header Required by Context Missing) in this case the context is SOAP. If
there is no existing HTTP error code that can be leveraged to indicate the
absense of a required SOAPAction header then maybe we need to ask for one to
be assigned - but i think it would need to be justified on the basis of more
general utility to the sorts of things layered above HTTP. 

It seems a little awkward to me from a spec. maintenance POV that a change
to the spec. of the SOAP/HTTP binding cascades a change in the HTTP spec. It
probably also sets a bad precident for other protocols layered over HTTP to
request/require error/status codes to suit their one specific purposes.
