FUML12 — The ReadLine::result parameter should have direction "return"

Specification: Semantics of a Foundational Subset for Executable UML Models (fUML), v1.1, RTF Beta (ptc/2012-10-18)
Subclause: 9.4.2 Pre-defined ReadLine and WriteLine Behaviors

The definitions for ReadLine and WriteLine in Subclause 9.4.2 do not give the multiplicity and direction for the parameters of those activities. However, one would expect them to be consistent with the multiplicity and direction for the corresponding parameters of the TextInputChannel::readLine and TextOutputChannel::writeLine operations. This is indeed the case as given in the normative fUML_Library.xmi, except for the result parameter of the ReadLine, which has direction “out”, while the readLine operation result parameter has direction “return”.

Change the result parameter direction to return

Agreed that the ReadLine::result parameter should have direction "return".
