I would say
(f1|f2|f3)*
will do the same thing and will be more efficient for the validator!
So, this will do the job:
<choice maxOccurs="unbounded">
<element name="field1" type="tns:type" />
<element name="field2" type="tns:type" />
<element name="field3" type="tns:type" />
</choice>
Thx,
-Stanley
