issueNumber

the issue number of the data module or data management list.
for data modules:
Every approved issue of a data module must be allocated an incremented issue number which, with the data module code, uniquely identifies that instance of the data module. The initial issue must be numbered with the value "001", which must be incremented with every approved release of a data module.
for data management lists:
Every issue of a data management list receives a consecutive number. The initial issue is numbered 001.
