Issue 12573: QVT 1.0 9.18 Missing transformation extension concrete syntax (qvt-rtf)
Source: Model Driven Solutions (Dr. Edward Willink, ed(at)willink.me.uk)
Nature: Uncategorized Issue
Severity: 
Summary: There is no support for transformation extension in the QVT Core concrete syntax.


Suggest: re-use the concrete syntax of QVT Relation, allowing "extends x" to follow
a transformation declaration.


example:


transformation yy::umlRdbms {
        middle imports tuml2rdbms;
        uml imports umlMM;
        rdbms imports rdbmsMM;
} extends base1, xx::base2, base3
Resolution: Simple change. Names are left vague pending resolution of Issue 10935.
Revised Text: In 9.18 Concrete Syntax change
Transformation ::=
“transformation” TransformationName “{”
( Direction“;” )*
“}”
to
Transformation ::=
“transformation” TransformationName “{”
( Direction“;” )*
“}”
[ “extends” TransformationName (“,” TransformationName)*]
