I agree, but would put it slightly differently:  as we've all said 
repeatedly, schemaLocation is a hint.  It's a hint.  It's a hint. 
Processors can ignore any or all schemaLocations if they so desire.  They 
can therefore choose to ignore relative ones, among others. 

 A reasonable interpretation of RFC 2396, section 5.2 [1], is that a 
schema processor designed in conformance with general web URI architecture 
will indeed interpret the relative URI as Henry suggests, if it chooses to 
honor the hint at all.  The schema specification does not restate or 
reinterpret the usual rules for handling URIs on the Web, except when 
schema-specific issues arise.
