  <!--
    This XSD is a modified version of the one found at:
    https://github.com/plutext/docx4j/blob/master/xsd/mce/markup-compatibility-2006-MINIMAL.xsd

    This XSD has 2 objectives:

        1. round tripping @mc:Ignorable

			<w:document
			            xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
			            xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main"
			            mc:Ignorable="w14 w15 wp14">

        2. enabling AlternateContent to be manipulated in certain elements
           (in the unusual case where the content model is xsd:any, it doesn't have to be explicitly added)

		See further ECMA-376, 4th Edition, Office Open XML File Formats
		Part 3 : Markup Compatibility and Extensibility

  <!--  Objective 2 -->
