Except that on Windows, a file path beginning with a drive letter and a 
":" is well-known to indicate an absolute path.  Some processors kindly 
make use of this knowledge (like Spy), and some do not (which both of us 
appear to agree is rfc-correct behavior)

Agreed - on a Unix-like machine.  Not on Windows.  On Windows a file 
d:\temp\xsd\schema.xsd is unambigously an absolute file reference on the 
local machine, and a file at \\mars\d:\temp\xsd\schema.xsd is 
unambiguously an absolute reference to a file an the host
"mars".  You cannot get a legal relative path just by leaving off the 
"file:///" part.
