* 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.
'''Example:''' map XML element ''id1'' to property ''ID1''
<source lang="xml">
<Identifier>
<id1>ID1</id> Map XML element id1 to property ID1 <id2 LogicalAND=”0”>ID2</id2> Concatenate identifier with OR <id3 UsesGuid=”1”>ID3</id3> Use a Guid as key value
</Identifier>
