55.4 Special case: adding a comment, no conversion
If you want to leave a node - for example a Check image node - unconverted,
but still add a comment or doctags to its Comment
(see Setting a comment/doctags), you can specify the node
in a Procedure call definition with qfs.do.not.convert as the
Procedure name. Definitions with this Procedure name
can also be used to explicitly exclude certain node sequences from conversion.
