In those "r" prefixed expression attributes, "wi" and "fe" are
available, being respectively the current workitem and the current
flowexpression.
You could thus do
<wait runtil="Time.now >=
fe.get_engine.process_status(fe.fei.wfid).launch_time + x" />
but maybe the intention is just
<sleep for="x" />

It's more economical than fetching the process status (an operation
that has to query the expression storage... with a cache on, it's not
a big problem though).
