As demonstrated by CSS2 (and, in fact, most widely used specifications), 
even being a REC is not a guarentee that things won't change. CSS2.1 
represents the CSS working group's most up-to-date published thnking, and 
as such can be considered as authoritative as any CSS spec can.

My deepest apologies for not replying sooner.

This was filed as issue 84. The working group considered the issue but did 
not feel that it was a problem, and further felt that it was raised too 
late in the process (after the publication of the CR spec) to be seriously 
considered (especially since vendors have already begun using this syntax 
for their extensions) .

In particular, if I recall correctly, the working group did not consider 
it a problem that functions could not be prefixed by unary operators. The 
example given in the e-mail cited above is most likely to be addressed as 
follows in CSS3:


...instead of:


No other use cases for unary operators were immediately apparent.

This is issue 128. The working group has not yet discussed it, but will 
probably resolve it as a duplicate of the earlier issue.
