Yes, but there are still at least 2 cases when I don't have the URL:

1) suppose a.xsd and b.xsd are not files. Suppose I supply them as InputSource in my custom Entity Resolver (They are in my database as strings). When my Entity Resolver is requested to resolve c.xsd, how should it know which one?
2) if in a.xsd and in b.xsd I have <xsd:include schemaLocation="c.xsd"/> - where is the URL ?

I don't understand: surely the two c.xsd files must have different
(absolute) URLs -- you can't have two different files with the same
URL. "c.xsd" should be resolved relative to the URL of a.xsd when it's
referred to in a.xsd, and to the URL of b.xsd when it's referred to in
