Too much detail? How would it be rendered. I think therr is little point 
in adding information that no one would ever use.

Additional tags such as temperature:range can be proposed and discussed 
after the temperature= tag is passed or rejected.. no point in 
discussing them if temperature= tag is rejected.

as in the source= tag? There are many additional tags that could apply 
to a single node with a temperature tag ... e.g.


stating them all ? Why? I'd think that confuses the merit or otherwise 
of the temperature tag.

I'd do source:temperature=   not temperature:survey_date:comment=Threw 
water on the rocks here, and it boiled away within seconds. Again .. 
adds nothing to the discussion on the temperature= tag.

Cannot dates be had from the history?
