This is a problem I encountered whilst working on a configuration XSD at work, I wanted to have a node that had content, with an enforced type along with attributes.  An example of the XML I wanted to allow is below.

<Quotes>
    <Quote author="George W. Bush">Rarely is the questioned asked: Is our children learning?</Quote>
</Quotes>

To specify a type for the node contents as well as some attributes, we need to use a type extension, specifying the type we want for the content as the base type.   This is shown below.

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:element name="Quotes">
      <xs:complexType>
        <xs:sequence>
          <xs:element name="Quote">
            <xs:complexType>
              <xs:simpleContent>
                <xs:extension base="xs:string">
                  <xs:attribute name="author" type="xs:string" />
                </xs:extension>
              </xs:simpleContent>
            </xs:complexType>
          </xs:element>
        </xs:sequence>
      </xs:complexType>
    </xs:element>
  </xs:schema>

The XSD above will permit the XML we want, and allow content and attributes on the same node.  I'll probably do some more stuff on XSDs in the near future.
