What really hurts is that Apache's own standalone schema parser only 
uses URI entries to resolve schema components. For our RSuite product we 
had to implement our own resolver that falls back to system entry lookup 
so that catalogs that work with documents also work when parsing those 
documents' schemas in isolation (DITA schemas being our primary use case 
for this).

Argh.
