3.57.5.Fixed Order: All Elements Required
<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
  targetNamespace="http://www.java2s.com" xmlns="http://www.java2s.com"
  elementFormDefault="qualified">

<xs:element name = "Count">
   <xs:complexType>
      <xs:sequence>
         <xs:element name = "One" type = "xs:string" />
         <xs:element name = "Two" type = "xs:string" />
         <xs:element name = "Three" type = "xs:string" />
      </xs:sequence>
   </xs:complexType>
</xs:element>
</xs:schema>

So the following example would be a conforming structure:

<Count>
   <One></One>
   <Two></Two>
   <Three></Three>
</Count>

But this would not:
<Count>
   <Two></Two>
   <One></One>
</Count>
