It is used by the system extension "impexp" to store some information. .. code-block:: php 'tx_impexp_origuid' => [ 'config' => [ 'type' => 'passthrough' ], ], .. _columns-passthrough-properties: .. _columns-passthrough-renderType-default: Properties renderType default ============================= .. _columns-passthrough-properties-type: .. _columns-passthrough-properties-default: .. include:: ../Properties/CommonDefault.rst.txt
