Hi

Your question is far from clear, and probably better asked on the OCL newsgroup.

If you want to use OCL just like any other metamodel, import (the old) OCL.ecore, or (the new) Pivot.ecore just like any other metamodel.

If you want your DSL to support OCL expressions, then you need to extend the OCL grammar, you can find examples in the QVTd project, but it's not easy. There is quite a bit of work to provide the automation to make use of OCL as an Xtext grammar sub-language as easy as use of Xbase.
