    initial v1  
    77Anyrate this all looks good except I think we should avoid the ST_Transform.  The reason is that the intersection checks require the geometries to be in the same spatial ref so would fail when acutally checked.

    9 In the case of multiple SRIDS, I think the Extent constraint should just be chucked as it's bound to do more damage than good.
     9The other reason to avoid ST_Transform is that some spatial refs transforming to others doesn't always make sense.  For example if your data uses UTM spatial refs.  Transforming from one UTM to another especially one that is far away doesn't make much sense since the bounds you'd get for the srid are invalid.
