CMLR-569 — Item completeness error
The item currently being defined has more elements entered than it should has, indeed. Usually, this error is caused by wrong value of a branching element, or by misinterpreting of some optional element.
Check your item format according to a proper section 5 manual page or by hint of C3H.
The exact CML path to the configuration node where the error occurs (interactive case) or line and character number (file case) is printed at the beginning of the message (before the colon).
