RE: [Springframework-developer] Spring bean factory XML format

What about mixing references and values in a collection? Would it look = as follows: <bean id=3D"foo"> <property name=3D"moo">moo</property> <property name=3D"coll"> <element refid=3D"alpha"/> <element refid=3D"beta"/> <element>gamma</element> </property> </bean> Rod's proposed syntax would be like this: <bean id=3D"foo"> <property name=3D"moo">moo</property> <property name=3D"coll"> <ref refid=3D"alpha"/> <ref refid=3D"beta"/> <value>gamma</value> </property> </bean> I tend to prefer the latter, as it clearly separates references and = values.
