A321 flight crew reported being advised by ATC that the SERFR2 arrival would take them below class B airspace. The design of this arrival caused them to momentarily exceed the speed requirement below class B airspace.

Narrative:
While descending via the SERFR2 star and approaching eddyy intersection I was notified that I will be below class B airspace for the next 1/2 mile. The current speed constraint was 240 kts which meant I was above the 200 kt limit below class B airspace. It happened because the STAR published altitude constraints didn't respect the class B floor. Have the class B vertical limits printed on the STAR chart if the STAR altitude constraints are below the floor.
