Query has all the include options of getChildren. For queries where the select clause contains properties from only one virtual table reference (e.g., referenced object type), the include options MAY be used. If the include options are used, the repository MUST include the information from the object type reference whose properties are specified in the select clause. If the select clause contains properties from more than one object type reference, the repository MUST/SHOULD throw an exception. also clarify reference terminology in query section (e.g., define object type reference)
