Maybe, but surely the XML spec isn't the right place to provide such a
thing.  There's nothing specific to XML about redirection.  People shouldn't
have to have an XML client in order to do redirection.  It should be
something that's handled at the HTTP level: the HTTP server should be able
to recognize when there is a redirection and should generate the appropriate
302 response, which the client can handle also at the HTTP level.

I am sure these can be improved on:

Behave		Show	Actuate	Explanation
REF		REPLACE	USER	Like <A HREF="...">
REF-NEW		NEW	USER	Like <A HREF="..." TARGET="_new">
HIDE		INCLUDE USER    Something you can click on to reveal
REDIRECT	REPLACE	AUTO	User-level redirect
NEW		NEW	AUTO	Creates a new window
EMBED		INCLUDE	AUTO	Like IMG

I'm not very clear about the intended behaviour of SHOW=NEW ACTUATE=AUTO.
Suppose I have one of these links at the end of a long document.  Is the
window created when the document is loaded or when I scroll down to the end
of the document? If the latter, does it automatically disappear if I scroll
back to the beginning?  What user requirement are we trying to meet here?
Unless there's a clear user requirement for this, I think we should dump it.
My current feeling is we show have a single attribute with just four values:
REF, REF-NEW, HIDE and EMBED.
