Here's the def of endType and its base elementType...

	<!-- Content Objects -->
	<complexType name="elementType" abstract="true">
		<annotation>
			<documentation>Abstract base type for content
objects (ends, links, references)</documentation>
		</annotation>
		<sequence>
			<element name="properties"
type="vlvx:elementProperties">
				<annotation>
					<documentation>Properties available
for visualization and/or application specific use. Users can extend by
deriving elements from elementType, and properties from elementProperties
without breaking compatibility with the vlvx document type.</documentation>
				</annotation>
			</element>
			<element name="reference" type="vlvx:referenceType"
minOccurs="0">
				<annotation>
					<documentation>Locates a reference
to this element (e.g. in a document).</documentation>
				</annotation>

			<element name="vlvf" type="vlvx:vlvfFragmentType"
minOccurs="0">
				<annotation>
					<documentation>Optional override of
default VLVF directives. Any ids in this fragment MUST match the
corresponding id attributes of referenced ends or links etc.</documentation>

		</sequence>
		<attribute name="id" type="ID" use="required"/>
		<attribute name="type" type="CDATA" use="required"/>
		<attribute name="metaItem" type="boolean" use="default"
value="false"/>
	</complexType>
	<!-- Element Properties -->
	<simpleType name="property">
		<annotation>
			<documentation>Properties are represented using
elements with limted types, or restrictions of those types (e.g. ranges or
enumerations). We may choose to extend the range of types, and or to provide

				</annotation>
			</element>
		</sequence>
	</complexType>

	<complexType name="endType" abstract="true">

			<documentation>Content object: end</documentation>
		</annotation>
		<complexContent>
			<extension base="vlvx:elementType"/>

	</complexType>

PS I simplified the instance by removing the "type" attribute from my
sample. The unadulterated instance was...

		<ends>
			<end id="e0001" type="???isThisRedundant"
xsi:type="vlvx:miscEnd">
				<properties>
					<displayName>end e0001</displayName>
				</properties>
			</end>
		</ends>
