>
> UpdateAttribute's genesis predates expression language, and as originally
> created would have made failure . As a result, when EL was introduced, there
> was also a means wherein the processor could fail. Currently, there is no
> failure relationship. As a result, the only way to remove files that are
> failing due to an EL issues and placed back onto the queue is through an
> expiration on the incoming connection. One particular instance is that of
> formatting a bad date input. Template showing example to follow.
> It could be the case this is a deficiency in just this particular EL
> function, but should EL become an extension point, it is entirely conceivable
> that failure cases become an occurrence that needs to be handled.
