/*
The NUMRM structure is used to track revision marking data for paragraph
numbers, and is stored in the PAP for each numbered paragraph. When revision
marking tracking is turned on, we fill out the NUMRM for each number with
the data required to recreate the number's text. Then at display time, that
string is compared with the current paragraph number string, and displayed
as changed (old deleted, current inserted) if the strings differ. The string
construction algorithm is the same as for an LVL structure.
