F.3. Jackrabbit XML Format

The hierarchical database also supports the older non-standard Jackrabbit format for defining node types, and only to make it easier for people to switch from Jackrabbit to the hierarchical database. The Jackrabbit 2.x no longer uses this format, and Jackrabbit 1.x only used this XML format for built-in node types and discouraged users from modifying it. However, some users of Jackrabbit 1.x still added their custom node types to this file.

Warning

Use the standard CND format wherever possible, and use this non-standard XML format only if you're trying to switch from Jackrabbit to the hierarchical database (with as little work as possible). If you are using the hierarchical database, you will need to convert your XML files to CND files.
The DTD for the non-standard XML files can be found here .
