2.9.59 DofrFsnp

Office

The DofrFsnp structure marks the beginning or end of a group of child frames. In the first marker, fPush is set to "true"; in the ending marker, fPush is set to "false". The enclosed child frames belong to the frame associated with the record that appears immediately before the DofrFsnp, with fPush set to "true".

DofrFsnp records can be nested. While loading the child nodes of frame A there appears another DofrFsnp with fPush set to "true". This means that the most recently loaded child record B does have child nodes. All the nodes between that DofrFsnp and the corresponding DofrFsnp with fPush set to "false" are the child nodes of frame B. This is how frame records support an arbitrary level of nesting within the frame set.

DofrFsnp records MUST be equally matched. There MUST be as many records with fPush set to "false" as there are records with fPush set to "true".
