Hello Simon and anyone interested,

re-opening the trac ticket #112 (see [1]) we thought about the problem
of different ocp codes again. We propose a new element <designator> with
the parameters 'register' and 'entry'. Using this new element, it will
be possible to address "local" register codes for the same <ocp>.

Example:
<ocp ...>
<designator register='IBNR' entry='8509404'/>
<designator register='DB640' entry='Bc'/>
<designator register='Ril100' entry='XSBU'/>
<designator register='DIDOK' entry='BU'/>
</ocp>

There are also different versions of certain registers, e.g. one for
each year. An optional attribute for the publishing date may be helpful.

Any comments appreciated...
