Indeed not -- I didn't intend to suggest that it did.

My message was intended as encouraging remarks from the sidelines, 
describing what, as you put it, neighbours decided on the same issue.  I 
(or indeed we) would be particularly interested in any comments on those 
conclusions, from this community, but we claim no authority here.

That document [1, Appx C.1] does, by the way, describes some apparent 
ambiguities in the FITS spec's description of its units syntax, which 
emerged when I tried to develop a machine-readable grammar for the 
syntax.  I mention this here to log it with the community.

Best wishes,

Norman
