misc description

## Description

The misc element is an all-purpose element to store information not covered by the other elements. For reasons of consistency, a reference database administrator should figure out rules which kind of information should be stored in the misc element.

The type element can be set to one of "1", "2", or "3", thus allowing to use 3 different misc elements per dataset.
