Purpose of outline's "Table of Contents"?

[Daniel]

I am wondering what the purpose of the "Table of Contents" in the 
Outliner is. Is it supposed to show those elements that actually appear 
in the "Table of Contents"? Or all "Sectioning"/"Headings" independently 
of whether they actually appear in the TOC.

Currently, it seems to rather do the latter than the former because it 
also lists "starred" sectioning entries that don't go into the TOC. 
Maybe a renaming would be worthwhile in order to not confuse the two?
