unfortunately wikipedia expressly says:
"There is no universally accepted definition of a hot spring. For example, one can find the phrase hot spring defined as:"
- a dozen of possible definitions which I won't copy here. (http://en.wikipedia.org/wiki/Hot_spring#Definitions)
Should that preclude us from mapping them even though they are locally well
known as hot springs?

wanting to relax in one is not really a definition of a hot spring.

we might think about an optional temperature tag but in my opinion it would be
one of the more problematic tags. The temperature may not be exactly known
or may be variable. People would start adding it to lakes and oceans:)

geothermal=yes would be closer. But in a strict sense this would exclude springs
with volcanically heated water.
