Hi, In the catalog for the XML Spec framework, one can read the following rule (that's actually the only rule): <rewriteSystem systemIdStartString="http://www.w3.org/XML/1998/06/" rewritePrefix="./"/> While in the DTD (it seems all other schemas have been generated from the DTD,) there is the following statement: TYPICAL INVOCATION: # <!DOCTYPE spec PUBLIC # "-//W3C//DTD Specification V2.10//EN" # "http://www.w3.org/2002/xmlspec/dtd/2.10/xmlspec.dtd"> So I wonder if the URIs are actually in sync. Shouldn't the catalog contain instead the following rule: <rewriteSystem systemIdStartString="http://www.w3.org/2002/xmlspec/dtd/2.10/" rewritePrefix="./"/> Besides this point, if I am right, rewriteSystem is not suitable for stylesheet URI resolution. So shouldn't we have to add the corresponding rewriteURI rule too? (whatever the URI actually is) Regards, -- Florent Georges http://www.fgeorges.org/
