This is totally user error: I should have been using system entries 
rather than public entries.

[But in fact now that I think back on it, I remember now that there is a 
design bug in how Xerces implements catalog resolution in that they use 
their entity resolution framework to resolve URIs for schemas, which is 
just wrong. However this behavior is so deeply embedded in the code that 
it would be very difficult to change it without a serious refactoring. 
In addition, they provide no way to do automatic recursive resolution of 
URIs via a catalog, which the catalog spec clearly says you should do or 
at least enable via your catalog resolution API.]
