 * Hi There, I’m trying to migrate custom CMS content with user comments into WP.
   
   I have seen the XML format file example here:
 * [http://google-blog-converters-appengine.googlecode.com/svn/trunk/samples/wordpress-sample.wxr](http://google-blog-converters-appengine.googlecode.com/svn/trunk/samples/wordpress-sample.wxr)
 * But don’t fully understand how all of the values work. `
    Is there a specification
   somewhere that explains what values are required, what can be left out etc to
   still be able to import content? Specifically these meta values
 *     ```
       <wp:postmeta>
       <wp:meta_key>_edit_lock</wp:meta_key>
       <wp:meta_value>1210966825</wp:meta_value>
       </wp:postmeta>
       <wp:postmeta>
       <wp:meta_key>_edit_last</wp:meta_key>
       <wp:meta_value>2575641</wp:meta_value>
       </wp:postmeta>
       ```
   
 * And
    `<wp:comment_id>8</wp:comment_id>` – Iif I leave blank will this be auto
   generated on insert?
