SEP REQT with all datum references at RMB/nonsize

[Burunduk]

In this video the speaker says at about 5 minutes mark that simultaneous requirements can only be overridden by a notation such as SEP REQT when at least one of the referenced datum features is not at RMB.

I believe this interpretation is not derived from the Simultaneous Requirement definition in the Y14.5 section about datum reference frames, but from the unfortunate way this concept is discussed at the section about tolerances of position. Specifically, it's paragraph 10.5.4 and its subparagraphs that make it look like SEP REQT is only applicable with datum references at MMB/LMB.

Opinions?

Look at what Google can do - or reading the manual that came with the software you recently encountered:
