Argument definitions
 The utf8.overlong-sequence exception is triggered when a function of the OMUTF8
      library encounters an overlong UTF-8 encoding of a Unicode code point.
      
 To use utf8.overlong-sequence, you must import OMUTF8 into your program using
      an import declaration such as:
        
import "omutf8.xmd" prefixed by utf8.
