Navigate to and select a different DTD.
List Structured Documents command	Use this method to create a list of structured documents associated with the selected DTD in a Details view. This method may be convenient when you want to pin the view, sort or filter the list, or modify the presentation to add columns of interest to assist with selecting documents to change.	Issue the List Structured Documents command on a selected DTD to display a list of structured documents in a Details view, then select or multiselect documents from the list and issue the Change DTD command. Navigate to and select a different DTD.

Note: If migrating large numbers of documents to new DTDs, determine whether the new DTDs will be used frequently and should be cached. If old DTDs are currently cached, but no longer will be frequently used, remove them from being cached. See Caching Frequently Used DTDs.
