My point about that is that reading the use, here, is causing me to 
suspect that it is "too close" to the normative term.  That is, it's too 
easy for the reader to misunderstand whether the text is or is not being 
normative.

To repeat: the issue isn't formal clarity; the language is entirely 
precise that it is /not/ normative.  The issue is potential readability 
concerns in a potentially wide audience.  It's a psych issue...

See above.

I think that the recommended(...) non-normative vocabulary should have 
substantial cognitive separation from the reserved, normative vocabulary.

This is a kind of information coding redundancy, to make it more likely 
that a reader will not think they've read something normative.
