Question managed by a remote engine

This question behaviour uses web services to connect to other question engines like OpenMark or ounit, so that their questions can be used in a Moodle quiz.
Note: This plugin is no longer supported (since 2025).
Opaque ( http://docs.moodle.org/en/Development:Opaque ) is the Open protocol for
accessing question engines. It can be used to add questions to a Moodle quiz from third party assessment systems that support the protocol, like OpenMark or ounit ( http://code.google.com/p/ounit/ ) and possibly other question systems we don’t know about.
As well as this question behaviour, you aslo need the associated question type https://moodle.org/plugins/qtype_opaque .
