I don't think we do.
A french "agglomération" implies some speed limits (bellow 50km/h)
But speed limits doesn't imply you are in an agglomération.
An agglomération is more than that, and I don't think there currently is an
agreed way to tag them...

I would suggest something in the place=something format + name=x
And if the wiki doesn't give any clues, it might be that we just need someone
writing a proposal and start discussing that matter.

Do you mean roads as member of a relation ? I wouldn't advise to do that, but
maybe draw an area around the agglomeration, or, before that, start
discussing it on the wiki.

When a new tag is created, chances are that no software will reconize it right
away, but by explaining somewhere how you tagged it in a clear (and
unambigous) way then everyone doing a software will know how to recognize it.

That's the current state of recommendation, but maybe we could start
discussing it to see if that's a good idea to apply speed limits on roads
inside a bounding polygon
