          Encountered an invalid shelf index.

 The maximum size of 'X' is 'Y', but the given index is 'Z'.
     where X is the name of the affected counter, stream, or switch, Y is its
maximum size, and Z the given constant index.

Explanation
When a shelf is declared as either fixed or bounded, OmniMark verifies that a constant index lies within the shelf's
bounds.
