Sorting of XSD-based elements matching multiple correct orders

Example

The following XSD defines two distinct strict orderings of the same elements:

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <xsd:element name="Element1">
    <xsd:complexType>
      <xsd:choice>
        <xsd:sequence>
          <xsd:element name="A" type="xsd:int"/>
          <xsd:element name="B" type="xsd:int"/>
          <xsd:element name="C" type="xsd:int"/>
        </xsd:sequence>
        <xsd:sequence>
          <xsd:element name="C" type="xsd:int"/>
          <xsd:element name="B" type="xsd:int"/>
          <xsd:element name="A" type="xsd:int"/>
        </xsd:sequence>
      </xsd:choice>
    </xsd:complexType>
  </xsd:element>
</xsd:schema>

The following code assigns values to the child elements of the parent element:

uses examples.pl.gosu.xml.myschema.Element1

var xml = new Element1()
xml.C = 5
xml.A = 5
xml.B = 5
xml.print()

This code prints the following:

<?xml version="1.0"?>
<Element1>
  <A>5</A>
  <B>5</B>
  <C>5</C>
</Element1>
