About updating your topic and map shells
At this point, your process may vary. These instructions assume that you originally created your custom topic and map shells using the instructions provided in Integrating DTDs into the Content Store on the IXIASOFT documentation page. If you created your custom shells otherwise, you will need to apply these steps in an appropriate way to your shells. Contact IXIASOFT Support if you are not sure how to proceed.
Note: While these instructions are very detailed, you might find it just as easy to compare or "diff"
your topic or map shell and the copy of IxiaDitabase.dtd or IxiaMap.dtd found in
com.ixiasoft.dita13.dtd and simply do a manual merge on the files.
