To clarify: you would use XPG4.2 for the interfaces enabled with 
_XOPEN_SOURCE_EXTENDED (UX-shaded in XPG4.2, what the conform/ data calls 
XPG4), XPG4 for interfaces not UX-shaded in XPG4.2 (which generally would 
have been in the original XPG4; which the conform/ data misleadingly calls 
XPG3)?  And older versions where actually in those older versions.

I don't think we need to consider .1g (sockets) separately from .1-2001.
