- If a text format property defines the 'optional' attribute as true,
then the $required parameter that
is passed to \core\external\exporter::get_format_structure() should be
VALUE_OPTIONAL.
- If a default value is provided for a format property,
\core\external\exporter::get_format_structure() should pass the default
value to the external_format_value constructor.
- Added validation for external_format_value for the default parameter.
Debugging will be shown in case an invalid default value is passed.
- Amended unit tests for better coverage.
Add special handling for text fields with the CLEANHTML type. This should
be used when students and teachers can edit the same field (you can't trust those students).
Applies cleaning on submitted data, and on data stored in the DB before it is put back in an editing form.
