I do still think some token to indicate it is a macro is appropriate

I used "=" in my conceptual discussion this morning, but that obviously 
won't work because we alreadty use "=" in the guidelines.

How about @NAN@, @NULL@, @+INF@, @-INF@

Or [NAN], [NULL], and so on.

Or is there a general reason why some sort of tokens won't work?

(I should not that if there is no range provided, it is genereally 
assumed to be infinite in the current plugin implementations - in other 
words, the philosohy has been to ry and be diligent in providing limts 
whenever they can be)

Right - programs that are built for graphing would be expected to ignore 
such data. But that does not give license to design the guideline such 
that nothing but graphing can ever be done with the data.
