Hello list,
The ICC offers a dictType Metadata Registry see more at:

The complete definition can be found here:

It is possible to enhance the dictType with additional entries wich will 
be rgisterred later by the ICC.
This would allow e.g. to create an entry with the complete Gutenprint setup.

best regards
