+            <p>When set to <codeph>true</codeph>, this property enables a compatibility mode that processes key
+              references that contain only whitespace characters like earlier versions of DITA-OT (prior to version
+              4.2.4). This behavior is not correct according to the DITA specification, but this setting ensures that
+              existing content that relies on this behavior will be processed in the same way as in earlier versions.
+              Set this property to <codeph>false</codeph> to skip these references as intended in the DITA
+              specification.</p>
