Dear Patrik,
the attribute profile is intended to use pre-defined set of attributes at different instances (re-use of attribute information as profiles).
The representation can not be further changed as it is part of the profile itself. The referencing attribute follows the same syntax as for AttrReps (see here https://www.adoxx.org/live/adoxx-attribute-notation-language-attrrep) and can be disables.
I'm sorry, I have troubles understanding the second part. So I can specify in the referencing attribute ("Reference to MyAP") how the Details of the referenced Attribute Profile (an instance of "MyAP") should be presented in the Notebook of the Object?
