/**
* PUBLIC:
* <p><b>Purpose:</b>Provide a mapping that can map a single attribute to a number of
* different elements in an XML Document. This will be used to map to Choices or Substitution
* Groups in an XML Schema
* <p><b>Responsibilities:</b><ul>
* <li>Allow the user to specify XPath {@literal ->} Type mappings</li>
* <li>Handle reading and writing of XML Documents containing a single choice or substitution
* group element</li>
* </ul>
* <p>The XMLChoiceMapping allows the user to specify a number of different xpaths, and types associated with those xpaths.
* When any of these elements are encountered in the XML Document, they are read in as the correct
* type and set in the object.
* <p><b>Setting up XPath mappings:</b>Unlike other OXM Mappings, instead of setting a single xpath,
* the addChoiceElement method is used to specify an xpath and the type associated with this xpath.
* <br>
* xmlChoiceCollectionMapping.addChoiceElement("mystring/text()", String.class);
* <br>
* xmlChoiceCollectionMapping.addChoiceElement("myaddress", Address.class);
