That seems to make sense, but isn't true in my experience.  I haven't used
the MS parser; I've used various parsers for Java and maybe a couple for
Perl and Python and the like.

In those parsers, if namespace recognition is turned on, a namespaced
instance can be validated against a namespace-less (by definition) DTD. 
Mixing namespaces is pretty impossible, but otherwise it works fine.  Both
of the given examples were validated.  Possibly I'm using different parsers,
or configuring them differently, though, than what you've seen.

According to Business Week, in the 1990s the ratio between a chief
executive's salary and the takehome pay of the typical, feckless, 
whining grunt on the shopfloor rose from 85:1 to 475:1. (In the UK, 
which is seeing a vigorous popular backlash against "fat cat" pay 
packets, the ratio is 24:1).
