Start new platform with QVTO installed. Create 'SimpleUML to RDB' sample project.

Add the following mapping to the end of the script:

mapping UML::Class::class2viewColumns(targetClass: UML::Class) : OrderedSet(RDB::view::ViewColumn) {
    init {
    	var v := object RDB::view::ViewColumn {};
        result := self.map dataType2columns(targetClass)->
            union(self.map generalizations2columns(targetClass))->asOrderedSet()
    }   
}

No error is reported.
However it faces two problems.
1. Creation of abstract type 'RDB::view::ViewColumn' should be prohibited
2. Assignment of collection(RDB::TableColumn) to collection(RDB::view::ViewColumn) is also invalid
