Yes, our position was that removing a class definition from a data store
should be prevented if there is still data of that class in the data
store. You have to delete the data first, then you can remove the class
definition.

Thanks,

Haris,

I'm not sure if that would be safe.
Considering that a feature class is not always mapped to single table,
but may be mapped to N physical tables, deleting data along with table
is potentially unsafe for data integrity.
