What you will want to do is have a simpleType that is restricted as an
Enumeration. Something like this:

  <xsd:element name="Types">
    <xsd:complexType>
      <xsd:sequence>
        <xsd:element name="Name">
          <xsd:simpleType>
            <xsd:restriction base="xsd:string">
              <xsd:enumeration value="Analog"/>
              <xsd:enumeration value="Digital"/>
              <xsd:enumeration value="Bus"/>
              <xsd:enumeration value="Undefined"/>
            </xsd:restriction>
          </xsd:simpleType>
        </xsd:element>
      </xsd:sequence>
    </xsd:complexType>
  </xsd:element>
