It's all very current (less than a week), based on the head versions
in the SVN. One of the next steps will be to make the XSLT use those
files directly out of the SVN, rather than the arbitrary directories I
put them in on my hard disk.
You're very correct to ask what versions the table is generated from:
that should be included information.

Another excellent question. It generally refers to a test where the
key is tested, but no specific value for the value. It might look like
"where highway is not null" or "<filter key="man_made">". It depends
on the specific file. The only exception is a rule I put in for OSM to
deal with that rule that had a set of several keys times several dozen
values. In that case I just ignore all the keys, and pretend they were

One of the major problems I'm facing is the size of the table
overloading mediawiki. Already I have to try saving the table several
times in some instances.
