--------------------------------------------------------------
Thanks for the comments all. Addressed most of the points raised and also fixed

# The client needs to know about this flag since it will be passed to the DN

# Vinayakumar, flags with bit values 0x1 through 0x8 are currently in use - see
CreateFlag.java. So the next available one is 0x10.
