Yep. Fortunately, given (1) (that namespaces-for-markup and
namespaces-for-content are kept separate), it's possible to change
prefixes without losing information that might be required for
interpreting content. And with a prefix retained, it would be possible
to use relatively meaningful prefixes in the merged document, such as
'xsl1' rather than 'ns0'.
  
Cheers,
