/**
 * 
 * Maps a JavaBean property to a map of wildcard attributes.
 *
 * 
 Usage 
 * 
 * The @XmlAnyAttribute annotation can be used with the
 * following program elements: 
 * 
 
 *    JavaBean property 
 *    non static, non transient field 
 * 
 *
 * See "Package Specification" in javax.xml.bind.package javadoc for
 * additional common information.
 * 
 * The usage is subject to the following constraints:
 *  
 *    At most one field or property in a class can be annotated
 *        with @XmlAnyAttribute.  
 *    The type of the property or the field must java.util.Map 
 * 
 *
 * 
 * While processing attributes to be unmarshalled into a value class,
 * each attribute that is not statically associated with another 
 * JavaBean property, via {@link XmlAttribute}, is entered into the 
 * wildcard attribute map represented by 
 * {@link Map}<{@link QName},{@link Object}>. The attribute QName is the
 * map's key. The key's value is the String value of the attribute.
