+  @param Str             The string representative of input device.
+  @param DevPath         The input device path structure.
+  @param DisplayOnly     If DisplayOnly is TRUE, then the shorter text representation
+                         of the display node is used, where applicable. If DisplayOnly
+                         is FALSE, then the longer text representation of the display node
+                         is used.
+  @param AllowShortcuts  If AllowShortcuts is TRUE, then the shortcut forms of text
+                         representation for a device node can be used, where applicable.
+
+  @return EFI_NOT_FOUND if no string representation exists.
+  @return EFI_SUCCESS   a string representation was created.
