> Currently TranQL supports the generation sql to execute a select for update.  Unfortunately, OpenEJB does not expose the ability in the current XSD to support this.  As a result the CMP implementation we have does pass CTS but lacks the ability to deploy an application that is performant and provides for data consistency.
> This improvement will add an attribute into the XSD for OpenEJB so a new attribute will be added <select-for-update> that is an indicator to use a select for update on a query so database locking can be employed.
> Changes will be made to TranQL (Syntax Factories) to create the correct SQL as well as OpenEJB's CMP builders to honor the request.
