This is patch no 1 that adds ids to various elements without making them
visible on the HTML surface.
It is an updated and rebased version of the work discussed in the
following thread:

https://www.postgresql.org/message-id/f900c5e1-a18a-84cc-6536-e85ec655c7d7%40gmx.de

The current statistics for docbook elements with/without ids after
applying the patch are the following:
