==== Special Note on Serialization of StructuredActivityNodes ====
In UML 2.3, it is not clear whether StructuredActivityNodes owned by an Activity should be serialized under the //node// or the //group// properties of that activity (or, strictly, even redundantly under both). The Valid XMI for this test case serializes such StructuredActivityNodes under the //node// property, which seems to be the most common choice. (The resolution of this issue in UML 2.4.1/MOF 2.4.1/XMI 2.4.1 results in StructuredActivityNodes being serialized under the //Activity::structuredNode// property, but this property is marked as derived in UML 2.3 and so would not normally be serialized at all.)
