[OpenLayers-Dev] bbox strategy and zooming

[Sebastian Benthall]

Just for the record, I've bumped into this exact problem with a client
recently as well.

Is there anything analogous to maxfeatures in other formats besides
WFS?  The only reason I can think of why it shouldn't be in BBOX is
that it might not be general enough.
