Re: ISSUE-74: Relative URIs in targetNamespace schemaLocation

Hi Paul,

I see your point.  I don't think we do much with xml:base!  I also think we 
need to differentiate between the different uses schemaLocation.

How about...

Basic Profile:
absolute URIs in @targetNamesapce
absolute URIs in xs:schema/@schemaLocation
relative URIs in [xs:import|xs:include]/@schemaLocation

Advanced Profile:
use of xml:base
absolute or relative (to base) URIs in @targetNamesapce
absolute or relative (to base) URIs in xs:schema/@schemaLocation
absolute or relative (to self or base?) URIs in 
[xs:import|xs:include]/@schemaLocation

Pete.

Hi Pete

I'd agree that a relative URI for schemaLocation is common, but
I'm concerned about support for xml:base in conjunction with such URIs.
How well is that likely to be supported?

Maybe a good way forward would be to allow absolute URIs in 
@targetNamesapce,
absolute and relative URIs in @schemaLocation, and warn about interactions
with xml:base?

Hi Paul,

FWIW our tool parses schemas that have been downloaded to local disk.
(Officially I guess we'd call it a local schema cache - or whatever XSD
would call it.  The user specifies the set of files in the cache - main
schema and those that are imported - and the schemas are compiled from
there.)

BUT... xs:include is slightly different and the tool works out where the
file is from schemaLocation attribute (is that the one I mean?).  Hence
relative URIs work for us better in this context.

So (similar to Paul Kiel's message) from our point of view, relative URIs
would be better (Basic?) in xs:include.  We don't really care what they are
in any other place!

Pete.
