Can AutoCAD access user attributes defined in the CAD Writer and written out on *non*-block features, and, if not, of what use is the FME functionality that allows this?

This question is in follow-up to this earlier post, which is, so far, unanswered ... After consulting with some CAD colleagues, I am starting to think that user attributes added to plain features (in my case points), not blocks, by the CAD Writer are invalid for AutoCAD. In fact, a Google search turned up no mention of user attributes outside of blocks ... and opening the output CAD file in FME shows no sign of the User Attributes defined in the Writer. Sigh.
