SYSML2_ — Interface usage cannot redefine inherited attributes in textual syntax

For some reason, the textual syntax for interface usage limits the set of elements allowed in its body (see InterfaceBody in clause 8.2.2.14.1). This prevents users from redefining inherited attributes in the usage:

interface myInterface : MyInterfaceDef // MyInterfaceDef defines attribute x
  connect end1 ::> end1InOuterScope
  to end2 ::> end2InOuterScope {
    redefines x = 5; // syntax error
  }

Defer to RTF

This issue was submitted after the end of the comment period, and the FTF has decided to defer its consideration to a future RTF.
