Ummm... no, that was the point *I* was making. :)

And I said that's not always possible - the app layer may have no idea about a malformed body content arriving.  We need to allow 4xx-6xx to be body *content* formatting errors too.  I.e., if you send me an INFO for a package "myXml" with body-part of C-T "application/xml" and that body-part's content is in fact just the string ":-P", I should be able to respond with a 4xx.  The question is what the xx should be.
