Steve Lawrence commented on DAFFODIL-2375:
------------------------------------------
Note that this issue is somewhat related to DAFFODIL-2324, since both deal with
how we select which branch choice to unparse when multiple branches have no
elements in them.

> Discovered this issue while working on a schema project.
> While the schema parses fine, for some reason multiple SetVariable parsers
> are getting instantiated for the same variable, which causes a double-set
> error to occur.
>
> See test_choiceBranchVariables in
> daffodil-test/src/test/scala/org/apache/daffodil/section07/variables/TestVariables.scala
> for a test that demonstrates this issue.
