 I don't either. An additional tag may be appropriate though.
 maxspeed=signals is mentioned on
 http://wiki.openstreetmap.org/wiki/OSM_tags_for_routing/Maxspeed#discussed_
 future_extensions but that would override any fixed maxspeed. Maybe
 maxspeed:variable=yes.

I'm using these tags:

maxspeed=variable

and to specify somewhat to give you a range on what to expect:

maxspeed:variable:max=50
maxspeed:variable:min=30

It's mostly being used here for zone 30's near schools where the signs are 
turned on when children are going to or coming from school, and also for 
highways with digital speed signals.

That sounds good; wonder what the Germans are doing on this given
they've had variable speed limits for over 40 years now.
