Re: [wsbpel] Issue - 95 - Proposal to Vote

[Dieter Koenig1 <dieterkoenig@de.ibm.com>]

No problem with "<rethrow/>" ...

Note that rethrow is not limited to <catchAll>. A <catch
faultVariable="xxx" faultMessageType="yyy"> also needs it as it does not
know the faultName.

Kind Regards

+1

Giving it a special name seems reasonable given its limited use.
