The CF standard names document contains an invalid standard name: "rate_of_
hydroxyl_radical_destruction_due_to_reaction_with_nmvoc" (containing a
space character) is used instead of the correct
"rate_of_hydroxyl_radical_destruction_due_to_reaction_with_nmvoc". This is
obviously a typo, and violates the standard name construction rules:
"Standard names consist of lower-letters, digits and underscores, and begin
with a letter." (

I discovered this problem in v35. I didn't dig through previous versions to
find when it was introduced, but the last CF email mentioning this standard
name that I can find was from March 2014.
