I think so. See <URL: http://www.flightlab.com/~joe/sgml/sanity.txt >,
which proposes a best-practice profile (called, in fact, "sanity").
The main points are:
* Do not bind a single prefix to different URIs at different places
* Do not bind a single URI to different prefixes at different places
* If possible, put all namespace declarations on the root element
To that I would further add:
* Do not use default namespace bindings
* If possible, do not use QNames-in-content
Documents that follow these rules avoid most of the problems
involved with namespace scoping. If documents can be
guaranteed to follow these rules, applications can be
considerably simplified (basically, it means they can
track the namespace environment on a per-document basis
instead of a per-node basis.)
