/**
 * XML Serializer example

 * This example demonstrates, how XML_Serializer is able
 * to serialize scalar values as an attribute instead of a nested tag.
 *
 * In this example tags with more than one attribute become
 * multiline tags, as each attribute gets written to a
 * separate line as 'indentAttributes' is set to '_auto'.
