/* Section */
* Values of identifier properties can have data type {{Guid}}
* If one identifier mapping has '''UsesGuid''' enabled, it will always be tried to load the object using its Guid. The other identifier mappings will be used only, if the XML object is missing a proper XML element for the Guid identifier.
{{Hint|Identifier attributes of reference and relation elements in the data file must be similar to identifier elements '''TargetType'''.}}
