Layer.Marker*s* is the class. Also, note that there is no such thing as
using a BBOX strategy, selectfeaturecontrol, etc. with a Markers layer;
it has a completely different way of handling interactions, as
described in
http://docs.openlayers.org/library/overlays.html#id4
(I'm also not aware of any way in which Markers are much faster than
vectors; generally it's the other way around, though that may not be
the case in all browsers.)
