Linking to the page where I documented the things I couldn't find isn't
very conducive to proving that the WMS is well documented ;)
The WMS for roads is not usable by anything other than tiling
mapservers. I understand performance limitations, but the fact that I
was more easily able to take an XML dump, load it into a PostGIS
database, and display segments that way myself, than I was to use
anything that OSM provides an interface for, does not say a lot on the
ability for others to use the WMS Output.
The link that Steve put in the wiki originally does not have the ability
to display streets.
The problem that I was running into, specifically, is the fact that the
extent limitations, as described in my edit last night, are not
documented anywhere other than in the code -- and even that wasn't
linked from the WMS page until last night.
So I spent 3 hours trying to manually generate *some* URI that would
include the streets in it -- and failing.
It was an extremely frustrating experience, when a simple mention in the
WMS page (as there is now) would have saved me hours of headache.
