EDIT

1. The render templates still refer to the old model in which protologues have been handled via name descriptions.
2. separate definition of microreferences makes no more sense --> remove these

CDM_PART_DEFINITIONS_DEFAULT:

 'descriptionPart' => array(
        'description' => TRUE,
      ),

CDM_NAME_RENDER_TEMPLATES_DEFAULT

'descriptionPart' => TRUE,

this should be changed to 'protologue'

Updating of all default (in code) and custom template definitions in the data bases is required
