Subject: [PATCH 5/7] Add SchemaNode::isOutput() method
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Organization: Wires

This commit introduces the `isOutput()` method to the `SchemaNode`
class, which checks whether the schema node is part of an output
statement subtree.

It complements an already existing `isInput()` method.
