A tarball would be good.

decodeClip5 is for pasteing attributes/operations/templates from the
UMLDoc::makeNewClassifierObject() does seem to make the umldoc the
parent which is possibly not the ideal way to do it. You could see if
it's possible to find the new parent UMLClassifier and make that the
parent or you could just leave it as it is and hope for the best (is
there are requirement to change the UMLOperation constructor or would
it just be neater?).
