From bug # 1085:

Jim, I've modified the standard html renderkit on this:

Issue: 1085

M doc/standard-html-renderkit-base.xml
M doc/standard-html-renderkit.xml

• Specify that the Messages renderer must render the id element if one
  is manually given by the page author.

Please let me know if this fixes the bug for you?
