I found Joe's pledge for sanity very helpful. For prefixes in content, 
it can be enough to save a document-wide mapping from prefixes to 
namespaces. Of course this does not allow redeclarations etc, and 
rightly so, I find.

The annoying exceptions can very clearly be marked by any implementation 
as not supported, and it is quite easy to turn an unsupported XML 
document into a supported one (changing, moving prefixes).

People *are* indeed always using the same prefixes (xsl, xsd, xsi...) 
and declaring them in the root...
