After you create your custom shell DTDs, you need to edit your plugin's catalog to reference
                those DTDs.
        - 
                Check out and open catalog.xml file (in
                        com.company.dtd).
            
- 
                Delete everything inside the first set of
                    <group></group> tags except for the following:
                
                    
                        - the <!--Topics--> comment
- the line that points to IxiaDitabase.dtd
- the <!--Maps--> comment
- the line that points to IxiaMap.dtd
 
 
- 
                Delete any other groups in the catalog.
                
                    You should be left with only the following in catalog.xml: <catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog" prefer="public">
	<group>
		<!-- Topics -->
		<public publicId="-//IXIA//DTD IXIA DITA Composite//EN" uri="dtd/IxiaDitabase.dtd"/>
		
		<!-- Maps -->
		<public publicId="-//IXIA//DTD IXIA DITA Map//EN" uri="dtd/IxiaMap.dtd"/>
		
	</group>
</catalog>
 
 
- 
                Change the publicId under <!-- Topics -->to match the
                    public identifier of CompanyDitabase.dtd and the uri value to
                        CompanyDitabase.xml:
                    <public publicId="-//COMPANY//DTD DITA Composite//EN" uri="dtd/CompanyDitabase.dtd"/>
 
 
- 
                Change the publicId under <!-- Maps -->to match the public
                    identifier of CompanyMap.dtd and the uri value to
                    CompanyMap.xml:
                    <public publicId="-//COMPANY//DTD DITA Map//EN" uri="dtd/CompanyMap.dtd"/>
 
 
- 
                Save and check in catalog.xml.
            
You now have your own catalog.
        
        
            Next, you need to reference your custom catalog in the IXIASOFT CCMS Desktop's master catalog.
