They are definitely not text insets. They are several lines in one Element. The line breaks are not Soft Returns, but are "full paragraph line breaks ("CrLf's"), with the Para symbol.
The parent elements mentioned in first post are set up as Container/Empty in EDD and so do not allow typing text. But they DO allow copy/paste text and/or structure.
Further testing since I started this thread has revealed: If I "rewrap" the two elements, all formatting gets stripped! The result looks very much like an Auto-Generated TOC that has not been set up for text formatting. That is, all the entries are slammed left, no leadered tab, and even the Across Cols gets stripped to where the entries are confined to the two-col page.

All I am seeing has now led me to suspect these lists were indeed created using a Book File - even if the book only contained the one document - then the results in the auto-gen list were copy/pasted into the top of the content file. Then formatted "manually". In fact, the Para Tags in use have conspicuously Auto-Gen TOC-looking names, such as, Title(TOC1)TOC. The context label you see in this example is indeed the one called out in the EDD!
I intend to test this stand-alone auto-gen theory tomorrow.

Thanks for the response.
