<game xmlns="http://actioncon.com/schema/gameinfo"
    productID="AY2344">
  <gtin>1234567890123</gtin>
  <title>Service Blaster 2000</title>
</game>

Example 6.1 - A simple XML document instance. The highlighted text represents an XML vocabulary comprised of three elements and
one attribute.


<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
  targetNamespace="http://actioncon.com/schema/gameinfo"
  xmlns="http://actioncon.com/schema/gameinfo"
  elementFormDefault="qualified">
  <xsd:element name="game" type="GameType"/>
  <xsd:complexType name="GameType">
    <xsd:sequence>
      <xsd:element name="gtin" type="xsd:string"/>
      <xsd:element name="title" type="xsd:string"/>
    </xsd:sequence>
  <xsd:attribute name="productID" type="xsd:string"/>
  </xsd:complexType>
</xsd:schema>

Example 6.2 - An XML schema that corresponds to the XML document instance from the previous example. The statements associated
with the highlighted name attributes give us an idea of how an XML schema defines the structure of an XML document.


<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
  targetNamespace="http://actioncon.com/schema/gameinfo"
  xmlns="http://actioncon.com/schema/gameinfo"
  elementFormDefault="qualified">
  <xsd:element name="game" type="GameType"/>
  <xsd:complexType name="GameType">
    <xsd:sequence>
      <xsd:element ref="gtin"/>
      <xsd:element ref="title"/>
    </xsd:sequence>
    <xsd:attribute name="productID" type="xsd:string"/>
  </xsd:complexType>
  <xsd:element name="gtin" type="xsd:string"/>
  <xsd:element name="title" type="xsd:string"/>
</xsd:schema>

Example 6.5 - gtin and title are declared as global elements.
