XTCE13 — ServiceRef construction error

The service ref now require content and an attribute – this clearly the result of an "oops" during clean up of 1.2.

Basically it should NOT extend NameDescriptionType.

<complexType name="ServiceRefType">
<annotation>
<documentation xml:lang="en">A reference to a Service</documentation>
</annotation>
<simpleContent>
<extension base="xtce:NameReferenceType">
<attribute name="serviceRef" type="xtce:NameReferenceType" use="required"/>
</extension>
</simpleContent>
</complexType>

Cleanup extra extensions from NameReferenceType

The reporter is correct in that there is a gratuitous extension in the schema for ServiceRefType. This will be cleaned up. The change here is not functional from the XTCE document standpoint. The document will be same.
