Hi,

I'm not the one that should be answering this, but I guess there's no 
harm. The registration message could have any nmwg schema compatible 
information, so if there's no field suitable in the current schemas you 
could add this field to the schema being used for the topology service 
and put it in the message.

The data element can be empty.

Regards,

Guilherme
