Relative URIs appearing in an XML document are always resolved relative

   Relative URI references are distinguished from absolute URI in that

I'd say the algorithm in RFC 2396 section 5.2 is applied to all URIs not 
starting with a scheme.

   This section describes an example algorithm for resolving URI

And that's why I think it well may be only the question what the base 
URI is.
