> 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.
