I've marked two of the entries as sic because the one marked film is not necessarily true. Scripted drama TV shows are shot at 23.976 here in the U.S. The NTSC as a generic label is wrong because there is no such thing as HD NTSC.
I just went through the specification and especially references to 720x576 (and notes) and I couldn't find anything that supports the "mandatory in PAL regions only" statement. About the only time regions are mentioned (other than things like text and screen regions) is where they are documented in tables or for playback control. On the other hand the A/V specification volume is well of 1400 pages long -- so saying anything definitively always has to come with the caveat "from what I could find".
