Kathey Marsden commented on DERBY-17:
-------------------------------------

See the specifications at:
http://www.opengroup.org/dbiop/
In particular, section 11.3.1 of:
http://www.opengroup.org/onlinepubs/9699959699/toc.pdf
for an explanation of the correlation token.

and the ACCCRDB and ACCRDBRM definition in
http://www.opengroup.org/onlinepubs/9699959499/toc.pdf

The client would also need to be changed to not send the correlation token on ACCRDB
