            Description:    This set of schematron rules have been created to increase the validation capability of the QTIv1.2.1 XSD.

                            A total of 12 rule sets have been created to ensure that:

                            [1]  Only valid Assessment metadata is defined;

                            [2]  Only valid Question types are defined in the Itemmetatadata fields;

                            [3]  The structure of a True/False question is correct;

                            [4]  The structure of a Multiple-Choice (Single Response) question is correct;

                            [12] The structure of the response processing feedback structure in an Item is correct;

                            [13] Generic features of an Item are correctly implemented.

                QTI General

                An Assessment object is the logical construction of the test.  An Assessment must

                contain at least one Section which in turn will contain Items and/or Sections.  An

                Assessment must eventually be constructed from a set of Items i.e. questions

                that are to be offered in the test.  An Assessment object contains all of the information

                to make the use of individual Items meaningful i.e. apart from the Sections the object

                includes the relationships between the Sections, the group evaluation processing and

                the corresponding feedback.

                Common Cartridge Profile

                The Assessment must consist of only one Section.  The only other permitted attributes

                are the mandatory identifier and title.  Optional language, metadata, rubric and

                presentation_material is also supported.

                QTI General

                A Section is the core grouping concept within QTI.  A Section consists of one or more Items or Sections (or

                references to Items and Sections).  In general, the objects contained within a Secton will have some relationship

                either in terms of content or content delivery.  The Section data structure is used to define arbitrarily complex

                hierarchical section and item data structures.  It may contain meta-data, objectives, rubric control switches,

                assessment-level processing, feedback and selection and sequencing information for sections and items.

                Common Cartridge Profile

                In Common Cartridge the Section can only contain a list of Items.  No metadata is permitted.  The identifier is

                mandatory but the title and language are optional.
