RE: XSV v XML Spy 3.5 beta 4 disagreement

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>
			<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>
				</annotation>
			</element>
		</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
additional types (i.e. restrictions of simple types).</documentation>
		</annotation>
		<union memberTypes="string long double date"/>
	</simpleType>
	<complexType name="elementProperties">
		<annotation>
			<documentation>The root base type for all element
property sets.</documentation>
		</annotation>
		<sequence>
			<element name="displayName" type="vlvx:property">
				<annotation>
					<documentation>Mandatory for all
elements.</documentation>
				</annotation>
			</element>
		</sequence>
	</complexType>

	<complexType name="endType" abstract="true">
		<annotation>
			<documentation>Content object: end</documentation>
		</annotation>
		<complexContent>
			<extension base="vlvx:elementType"/>
		</complexContent>
	</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>
