form 

Traditionally, the 'normal' mordent is written as a short wavy line with a
vertical line through it and the inverted mordent is written without the vertical line.
However, the meaning of these signs is sometimes reversed. See Read, p. 245-246. Another
attribute in the visual domain would be necessary in order to be completely explicit about
which visual symbol is actually to be rendered.
