There's no real way to override processContents="strict".  I think you just 
have to accept that the schema contains a bug in it.  As it happens using 
processContents = 'skip' is also the right way to go for including elements 
with namespaces.

One other thing, I've seen some reports of processors having problems with 
schemas that specify specific, but high values for maxOccurs (e.g. 50 as 
opposed to unbounded).  This is because they try to build a state machine 
with as many states as maxOccurs dictates.  I'm not sure at the point where 
the problems start arising, so maybe 50 is OK.  Just thought I'd mention it 
as something to bear in mind!

HTH,
