Jim, I disagree that it is 'endorsed' by the example. If it was endorsed, it would be in the Help pages. I know that Kay checked with Chris and Eowyn to make sure that the Help was correct and only those 4 headers should be 2 level. If the Help page is changed, then Kay would change her code, I am sure, but she has been very careful about following and reading every Help page that affected the Style issues she was addressing.
Hopefully, Someone from the Team will comment or give an answer to this post now that some tags have been added.
