Re: [xml] Confused: Handling relative paths in catalogs

I'm trying to work with files produced by the Domino XML toolkit,
which are of type: <!DOCTYPE document SYSTEM "domino.dtd">.  So I did
"xmlcatalog --create --add system domino.dtd /long/path/domino.dtd catalog"
and got:

<?xml version="1.0"?>
<!DOCTYPE catalog PUBLIC "-//OASIS//DTD Entity Resolution XML Catalog V1.0//EN"
<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog">
<system systemId="domino.dtd" uri="/long/path/domino.dtd"/>

   Well ... the semantic of this is unclear to me. systemId is supposed to
be an URI having it relative would make the reference to the catalog URL
ouch ...

The problem is that matching in the catalog apparently looks up
/path/to/document/domino.dtd instead of just domino.dtd.  Since only
prefix substitution is allowed, there doesn't seem to be a way to
match <anything>/domino.dtd.

The result is that this works fine:
  [/tmp/xml]0$ xmllint --valid --noout note.xml 

But this doesn't:
  [/tmp/xml]0$ xmllint --valid --noout /tmp/xml/note.xml 
  /tmp/xml/note.xml:3: error: failed to load external entity
  <!DOCTYPE document SYSTEM 'domino.dtd'>

  Can you provide the debugging output of the catalog resolution as explained at

Am I missing something? Is there a different way to handle the case
where the DTD is specified as a relative path?

  I don't have a clear answer, I just pointed Norman Walsh to this
he probably have the answer.
