I've done a schema cache implementation using Xerces-J. In cases where a 
schema location hint is provided, I compare both namespace and location. 
If a cache didn't use the location hint when provided, I would consider 
it to be broken unless the user had given specific instructions to 
ignore the hint.

But if no schema location is specified, which is perfectly legitimate, 
the cache will return any schema with the same namespace (or no 
namespace). Though this could cause problems, it seems to fit the usage 
patterns of people who do not like to specify locations, who tend to set 
up a 1-1 correspondence between schema and namespace.
