Re: My comments on the BP

Hi Andrea-

first time it is used, as done for "feature".

Given our vote to release the BP doc for FPWD as it was last night, I
missed the chance to process your request.

However, looking at the BP doc, I note that every time the term
"SpatialThing" is used, it's linked to the definition in the Glossary [1]
that comes straight from the Geo vocabulary [2] where it is defined.

I agree that for the next WD release, we need to work on better defining
the terminology we use ...
