>From the technical report, it seems that OWL-S 1.1 does not support 
OR effects.  However, it does support conditional effect, which may be 
used in your situation. Since OWL-S 1.1 uses other formats, such as
KIF, DRS and SWRL, to define the expression, you may also define disjunctive
predicates in it. But this will make the result of the process undetermined.
