Yeah, it takes two passes.  Better to declare up-front which namespaces 
to preserve...

I'm not keen on magic or specialness based on either (a) IE 
misbehavior, or (b) cocoon URIs.  Anyway, like you have said, this 
thing is starting to have too many options for "common feature of 
XML/HTML serializers"... I'm now leaning back toward the idea of a 
transformer.  The objection that it's onerous to include this 
transformer "in every pipeline" is weak, because (a) it doesn't have to 
be "in every pipeline", only in final presentation pipelines, and (b) 
you'd naturally factor that and the serializer into a <map:resource> 

How about a NamspaceTransformer, configured with

		<namespace prefix="prefix">URI</namespace>


1) If <null-namespace> is present, then the null NS is the default NS
2) Otherwise, the NS with @default="true" is the default NS (more than 
1 such = error, or > 0 if we have <null-namespace/>
3) @prefix is optional; if not set, then use the first prefix found for 
the NS
4) The transformer writes all the namespace declarations into the root 
element, deletes them from any descendant elements
5) If a namespace is found that is not in the configured <namespaces>, 
throw an error

How does that sound?
