Try this:

 <p:when test="not($env = ('sandbox', 'int', 'test', 'stage', 'live'))">
   <p:error code="wadl:envRequirementFailed">
 		<p:input port="source">
 			<p:inline>
 				<message>The option value provided does
 not match one of ('sandbox'|'int'|'test'|'stage'|'live').</message>
 			</p:inline>
 		</p:input>
 	</p:error>
 </p:when>

We added an output to p:error so that you wouldn't have to do all that
mucking around with a bogus output port from the p:when or p:otherwise.

                                        Be seeing you,
                                          norm
