A link that connects an information module to its administrative data in the admindata module
Each information module must have exactly one corresponding 'lnk.admin' link that connects it with its administrative data within the admindata module.
The first anchor point, 'Module', is always an information module. The second anchor point, 'Admindata' is always an element of the type 'moduladmin'.
