[oXygen-user] Setting up and using Catalogs for XSD-Based Documents

[W. Eliot Kimber]

I'm trying, pretty much for the first time, to configure Oxygen 8.1 to 
use a catalog to resolve noNamespaceSchemaLocation= values.

For example, I have this document root element:

<map xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:noNamespaceSchemaLocation="urn:oasis:names:tc:dita:xsd:map"
   >

(The URN is one I made up just for testing)

And this catalog:

<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog" 
prefer="public">

   <group xml:base="schema/">
     <uri name="urn:oasis:names:tc:dita:xsd:map"
       uri="map.xsd"/>

     <public publicId="urn:oasis:names:tc:dita:xsd:map"
       uri="map.xsd"/>
   </group>
</catalog>

Where schema/ is a directory below the directory containing the catalog 
and the files are there (that is, a document in the same directory as 
the catalog with this root element is valid:

<map xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:noNamespaceSchemaLocation="./schema/map.xsd">

I have turned on catalog verbosity and I can see in the catalogs tab 
that my catalog is being loaded, but I'm not sure what the "Public: " 
messages are telling me, but I'm seeing entries like this:

SystemID: null
Description: Public: null System: 
file:/C:/projects/DITA-OT1.3.1/schema/tblDeclMod.xsd = null

In any case, my document that uses the URN is not being validated--I get 
the "there is no schema or DTD associated with this document" message.

Is this user error or a limitation of the catalog mechanism?

Thanks,

Eliot
