It really should be red-flaging the document (death to all popups)
so that it is clear to the user that there was an error; but it's
good that it displays the document.

[you could always put a nice red-flag in the document itself :-]

That is just totally bogus; the information returned by the server
is potentially *critical* to the user to figure out what they have
done wrong.

Quoting from the spec [draft-ietf-http-v10-spec-05; Feb 1996]:
	9.4 Client Error 4xx

	...
	Except when responding to a HEAD request, the server should
	include an entity containing an explanation of the error
	situation, and whether it is a temporary or permanent condition.

[Of course, when el-users are at the helm it's usually permanent :-]
