my first thought would be that looping is not good. i would opt for a solution that makes it clear when expressions are resolved and when not. e.g. introduce a new attribute like: <variable name="defaultSubject" value-expr="[#{processDefinition.name} #{processInstance.id}] generated Mail" /> if you have an eclipse patch file for the latter solution including a test for both attributes (incl one showing that #{sdfsd} is not resolved when using the value), then we can include it quickly. otherwise it will depend on when (if) we have the time to include this improvement.
