Development:Import/export for questiontype plugins
From MoodleDocs
Motivation
While it is easy enough to add import and export capability for core questiontypes there is no clear way to allow contributed questiontype authors to enhance their plugin with import and export code. This is an outline proposal for including hooks for that functionality. It is primarily aimed at the Moodle XML format (the most comprehensive import/export format) but with a definite goal not to exclude any other format that may wish to use it.
