            Status:         Final
            Description:    This is the IMS GLC Meta-data v1.3 binding of the IEEE LOMv1.0.
                            This is a Strict binding of LOMv1.0.  The strict multiplicity of elements 
                            has been imposed and there is no furtehr constraint on the permited 
                            ordering.

            History:        Version 1.3: This replaces the IMS GLC Metadata v1.2.4 binding.

            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.
