<DD>Checks mutability of featureID for this transaction.
 
 <p>
 Two behaviors are defined by FeatureLocking:
 </p>
 
 <ul>
 <li>
 TransactionLock (Blocking): lock held by a Transaction<br>
 Authorization is granted to the Transaction holding the Lock. Conflict
 will result in a block until the Transaction holding the lock
 completes. (This behavior is equivalent to a Database row-lock, or a
 java synchronized statement)
 </li>
 <li>
 FeatureLock (Error): lock held by a FeatureLock<br>
 Authorization is based on the set of Authorization IDs held by the
 provided Transaction. Conflict will result in an error.  (This behavior
 is equivalent to the WFS locking specification)
 </li>
 </ul>
 
 <p>
 Right now we are just going to error out with an exception
