* 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.
* Indexed MetaProperties can additionally have an '''Index''' mapping attribute
* Use the '''Value''' attribute if a constant value shall be imported
* Set '''Validate = 0''' if the validation time stamp of a validated property should not be not during import and/or the property value should be always exported.
