In class & datatype confluence page there's a reference to (...) new classes already including the Recommendation datatype for demonstration purposes. (...). The package with these classes is referred has being located in the extensions doc folder.
This package has been relocated (an later removed?) from the distributed package.
Since the class adaptation is so simple to operate, maybe the documentation could be changed:
- remove the reference to the ezpk
- include step by step explanation on how to include ezrecommendation datatype on the example classe(s)
