ProcessIsReferencedOnDocument
=============================
.. rubric:: Description


This modelling pattern allows to express that a 
‘class of activity’ is referred to on a document.
No information about the type of reference is made - it could be symbolic,
textual or both.
It is assumed that, while parsing the information about the COAC from a 
data file, an entity for the underlying document can be found or is created
in a database that contains information about documents.


.. rubric:: Definition


A process (x1) is referenced on a document (x2).
