Using the results obtained in implementing OCL support in ROCASE3, and taking into account the conclusions obtained testing the tools mentioned at http://www.klasse.nl/ocl, the paper tries to analyze this state of facts. The requirements needed in order to obtain a strong OCL support are presented. The ROCASE OCL support beyond semantical analysis is presented by means of a real example. Finally the conclusions acquired in our activity are offered.enText/Conference Paper1617-5468
