Not sure what @bblay meant?
But I think it would be good to give more context here (in the std_names.py docstring) -- explain what it is derived from, like...
```
Produced from an XML description of CF standard names.
The definitive source for the XML files is:
    http://cf-pcmdi.llnl.gov/documents/cf-standard-names
```
(N.B. cribbed from the docstring of *this* file)
