The standard JAXP URIResolver is given a relative URI and a base URI and returns the resource identified by this combination. However, to support a stable implementation of the doc() function, Saxon needs to know what the absolute URI is before the resource is fetched, so it can determine whether a document with that absolute URI actually exists.
This extended interface defines a URIResolver that separates the two functions of resolving a relative URI against a base URI, and fetching a resource with that absolute URI. If the URI resolver supplied to Saxon implements this interface, the absolute URI associated with a loaded document will be the URI returned by this resolver.
The particular motivation for providing this interface is to allow a URIResolver to wrap a .NET XmlResolver, which has additional capability not present in the JAXP interface.
