reference from `cei:persName/@key` in single charter view to metadata.person.public entries works only for Illuminierte Urkunden.

Created by: GVogeler

In the illuminated charters project link between cei:persName/@key and metadata.person.public/*.tei.xml works fine with http://www.monasterium.net/mom/IlluminierteUrkunden/1330-10-08_Darmstadt/charter (see index in the end).

But there are already links external to the Illuminierte Urkunden project: http://www.monasterium.net/mom/index/CDC-notai/P_Aceprando-2 is based on cei:person/@key='' in http://www.monasterium.net/mom/atom/GET/metadata.charter.public/CodexDiplomaticusCavensis/0007.cei.xml but http://www.monasterium.net/mom/CodexDiplomaticusCavensis/0007/charter does not display an "i"nformation icon next to the index entry in end of the charter view.
