+            <dd>A service or implementation name used to instantiate the

+                is missing, the implementation selects an appropriate importer.
+                By default, a MergeImporter should be used.

+            <dt><code>OverwriteExisting</code> : `boolean`</dt>
+            <dd>If `TRUE`, specifies that no existing data should be
+                overwritten by the import. If the Importer used
+                does not support such protection, an error may be raised.
+                If some data is not imported, because there is existing
+                data, this is indicated by returning an appropriate exception.

+                If the Importer used does not support this
+                operation, an error may be raised.
+                By default, a CopyImporter is used to perform
+                truncating import.
+            </dd>
+            <dt><code>Entity</code> : `string`</dt>

+                which the imported data should apply. The value will be passed
+                to XLayerImporter::importLayerForEntity().
+                If this parameter is missing, the implementation uses
+                XLayerImporter::importLayer() instead.
+            </dd>
+            <dt><code>Component</code> : `string`</dt>
