(declare-flow-object-class formatting-instruction "UNREGISTERED::James Clark//Flow Object Class::formatting-instruction") (make formatting-instruction data: " ")
(element p
(sosofo-append
(formatting-instruction data: "&#RE;")
(process-children)))
Note that \n is not recognized as a newline character--you either need to
do as I do above and use &#RE; or actually embed a newline in the string.
You must declare the formatting-instruction flow object class before using
it:
(declare-flow-object-class formatting-instruction "UNREGISTERED::James Clark//Flow Object Class::formatting-instruction")
