Hi Shawn, This has come up on a few occasions [1]. In that last discussion I argued that relative URIs in the schemaLocation hints are relative to the resource in which they're actually dereferenced. Now I'm not so sure. You could argue that they're relative to the document entity or some base URI you've specified using xml:base. There doesn't seem to be anything in the spec [2] on how a schema processor should resolve realtive URIs specified in the schemaLocation hints.
I'm sure someone else on the list could provide more insight.
