I admit I am new to the Complete OCL.
I'd like to use it as a validation means instead of the XText default validation as described in this very nice presentation http://www.slideshare.net/EdWillink/enrich-your-models-with-ocl.
In this way I could exploit the same OCL to perform validation before further QVT/MOFM2T(ACCELEO) transformations.
To this end I have started with an empty .ocl file and I am trying to define the first import.
The problem is that it depicts this error:
Unresolved import 'http:/...' : White spaces are required between publicId and systemId.
