Reviewing Roger's example above, it seems XSV may
be looking for <xsd:element...> first.  For example:

  <?xml version="1.0"?>
  <xsd:schema xmlns:xsd="http://www.w3.org/2000/10/XMLSchema"
          elementFormDefault="qualified">

      <xsd:element name="Book" type="CardCatalogueEntry"/>

      <xsd:complexType name="CardCatalogueEntry">
          <xsd:sequence>
              <xsd:element name="Title" type="xsd:string"/>
              <xsd:element name="Author" type="xsd:string"/>
              <xsd:element name="Date" type="xsd:string"/>
              <xsd:element name="ISBN" type="xsd:string"/>
              <xsd:element name="Publisher" type="xsd:string"/>
          </xsd:sequence>
      </xsd:complexType>
  </xsd:schema>

This should validate.  Perhaps XSV considers
CardCatalogueEntry undefined because the parser
first expects a global/root element definition 
pointing to a complexType structure following
further in the schema.
