I have used source:maxspeed=sign to indicate collection from a physical speed limit sign during a survey, and agree with Ian that the previously cited cases are an acceptable use of source:maxspeed.<div><br></div><div>This is not the only case where multiple tagging schemes are used; it's one of the joys of crowd/community dynamics<br>

The general usage is according to the wiki:<br>
distinguish between implicit and explicit speed limits (i.e. the<br>
default maxspeed in the context (urban, rural, motorway) and sign<br>
posted limits). The idea is to always add maxspeed=number(unit like<br>
mph or kmh) to highways and to distinguish where the limit comes from<br>
with the additional key source:maxspeed.<br>

They are specifying the source for the speedlimit tag. They found the maxspeed value in a PDF somewhere.</div>
