MX
— deletion of a missing page query generated by the
execution of dfdelmpqc
Any missing page queries deleted by the
dfdelmpqc function during the execution of an
edit check are recorded in a MX.
Since missing page queries are never deleted from the current record,
a K child element is needed to identify the keys from
which the missing page query is deleted.
A MX element does not imply that a missing page query
was deleted from the database, simply that one would have been deleted
if the APPLY element had allowed query actions.
