            XSD Data File Information
            =========================
            Author:         Colin Smythe, IMS Global (UK)
            Date:           1st August, 2017
            Version:        1.0
            Status:         Final
            Description:    This is the LTI v1.4 Profile of the IMS Global Metadata v1.3.2 binding of the IEEE LOMv1.0.
                            This is for the metadata associated with resources in a LTI Link in a Common cartridge. 
                            This is based upon a combination of the Strict/Loose binding of LOMv1.0.

            History:        Version 1.0: The first formal release of this LTIv1.4 LOM for CC-based LTI-links.

            PROFILE:        This is the "LTIv1p3-CCLink". THIS IS A PROFILE OF THE BASE SPECIFICATION.
                            The changes to the base specification are:
                            * The schema namespace has been changed to "http://ltsc.ieee.org/xsd/imsccv1p4/LOM/imscclti".
                            * The schema version has been changed to "IMS CC MD 1.3.2 LTI 1.4".

            Schematron Strict Selection Validation Rules
            ============================================
            This is the set of Schematron rules that have been created to enforce the use of the "Unordered" stereotype.
            These rules ensure that the number of entries in an unordered complexType of an element obey the multiplicity constraints.
            This is required so that any-order/any-multiplicity complexTypes can be constructed and validated.
