Method to process a "remove" statement

Parameters:

ownerSM - StateManager for the owner

conn - The connection

batched - Whether we are batching it

element - The element

executeNow - Whether to execute the statement rather than allow batching til later

acs - The abstract collection store

Returns:

Number of records changed (0 if batch since nothing yet changed)
