 /**
  * Maps a JavaBean property to XML infoset representation and/or JAXB element.
  *
  * <p>
  * This annotation serves as a "catch-all" property while unmarshalling
  * xml content into a instance of a JAXB annotated class. It typically
  * annotates a multi-valued JavaBean property, but it can occur on
  * single value JavaBean property. During unmarshalling, each xml element
  * that does not match a static &#64;XmlElement or &#64;XmlElementRef
  * annotation for the other JavaBean properties on the class, is added to this
  * "catch-all" property.
  *
  * <p>
  * <h2>Usages:</h2>
  * <pre>
  * &#64;XmlAnyElement
  * public {@link Element}[] others;
  *
  * // Collection of {@link Element} or JAXB elements.
  * &#64;XmlAnyElement(lax="true")
  * public {@link Object}[] others;
  *
  * &#64;XmlAnyElement
  * private List&lt;{@link Element}> nodes;
  *
  * &#64;XmlAnyElement
  * private {@link Element} node;
  * </pre>
  *
  * <h2>Restriction usage constraints</h2>
  * <p>
  * This annotation is mutually exclusive with
  * {@link XmlElement}, {@link XmlAttribute}, {@link XmlValue},
  * {@link XmlElements}, {@link XmlID}, and {@link XmlIDREF}.
  *
  * <p>
  * There can be only one {@link XmlAnyElement} annotated JavaBean property
  * in a class and its super classes.
  *
  * <h2>Relationship to other annotations</h2>
  * <p>
  * This annotation can be used with {@link XmlJavaTypeAdapter}, so that users
  * can map their own data structure to DOM, which in turn can be composed
  * into XML.
  *
  * <p>
  * This annotation can be used with {@link XmlMixed} like this:
  * <pre>
  * // List of java.lang.String or DOM nodes.
  * &#64;XmlAnyElement &#64;XmlMixed
  * List&lt;Object> others;
  * </pre>
  *
  *
  * <h2>Schema To Java example</h2>
  *
  * The following schema would produce the following Java class:
  * <pre>
  * &lt;xs:complexType name="foo">
  *   &lt;xs:sequence>
  *     &lt;xs:element name="a" type="xs:int" />
  *     &lt;xs:element name="b" type="xs:int" />
  *     &lt;xs:any namespace="##other" processContents="lax" minOccurs="0" maxOccurs="unbounded" />
  *   &lt;/xs:sequence>
  * &lt;/xs:complexType>
  * </pre>
  *
  * <pre>
  * class Foo {
  *   int a;
  *   int b;
  *   &#64;{@link XmlAnyElement}
  *   List&lt;Element> any;
  * }
  * </pre>
  *
  * It can unmarshal instances like
  *
  * <pre>
  * &lt;foo xmlns:e="extra">
  *   &lt;a>1</a>
  *   &lt;e:other />  // this will be bound to DOM, because unmarshalling is orderless
  *   &lt;b>3</b>
  *   &lt;e:other />
  *   &lt;c>5</c>     // this will be bound to DOM, because the annotation doesn't remember namespaces.
  * &lt;/foo>
  * </pre>
  *
  *
  *
  * The following schema would produce the following Java class:
  * <pre>
  * &lt;xs:complexType name="bar">
  *   &lt;xs:complexContent>
  *   &lt;xs:extension base="foo">
  *     &lt;xs:sequence>
  *       &lt;xs:element name="c" type="xs:int" />
  *       &lt;xs:any namespace="##other" processContents="lax" minOccurs="0" maxOccurs="unbounded" />
  *     &lt;/xs:sequence>
  *   &lt;/xs:extension>
  * &lt;/xs:complexType>
  * </pre>
  *
  * <pre>
  * class Bar extends Foo {
  *   int c;
  *   // Foo.getAny() also represents wildcard content for type definition bar.
  * }
  * </pre>
  *
  *
  * It can unmarshal instances like
  *
  * <pre>
  * &lt;bar xmlns:e="extra">
  *   &lt;a>1</a>
  *   &lt;e:other />  // this will be bound to DOM, because unmarshalling is orderless
  *   &lt;b>3</b>
  *   &lt;e:other />
  *   &lt;c>5</c>     // this now goes to Bar.c
  *   &lt;e:other />  // this will go to Foo.any
  * &lt;/bar>
  * </pre>
  *
  *
  *
  *
  * <h2>Using {@link XmlAnyElement} with {@link XmlElementRef}</h2>
  * <p>
  * The {@link XmlAnyElement} annotation can be used with {@link XmlElementRef}s to
  * designate additional elements that can participate in the content tree.
  *
  * <p>
  * The following schema would produce the following Java class:
  * <pre>
  * &lt;xs:complexType name="foo">
  *   &lt;xs:choice maxOccurs="unbounded" minOccurs="0">
  *     &lt;xs:element name="a" type="xs:int" />
  *     &lt;xs:element name="b" type="xs:int" />
  *     &lt;xs:any namespace="##other" processContents="lax" />
  *   &lt;/xs:choice>
  * &lt;/xs:complexType>
  * </pre>
  *
  * <pre>
  * class Foo {
  *   &#64;{@link XmlAnyElement}(lax="true")
  *   &#64;{@link XmlElementRefs}({
  *     &#64;{@link XmlElementRef}(name="a", type="JAXBElement.class")
  *     &#64;{@link XmlElementRef}(name="b", type="JAXBElement.class")
  *   })
  *   {@link List}&lt;{@link Object}> others;
  * }
  *
  * &#64;XmlRegistry
  * class ObjectFactory {
  *   ...
  *   &#64;XmlElementDecl(name = "a", namespace = "", scope = Foo.class)
  *   {@link JAXBElement}&lt;Integer> createFooA( Integer i ) { ... }
  *
  *   &#64;XmlElementDecl(name = "b", namespace = "", scope = Foo.class)
  *   {@link JAXBElement}&lt;Integer> createFooB( Integer i ) { ... }
  * </pre>
  *
  * It can unmarshal instances like
  *
  * <pre>
  * &lt;foo xmlns:e="extra">
  *   &lt;a>1</a>     // this will unmarshal to a {@link JAXBElement} instance whose value is 1.
  *   &lt;e:other />  // this will unmarshal to a DOM {@link Element}.
  *   &lt;b>3</b>     // this will unmarshal to a {@link JAXBElement} instance whose value is 1.
  * &lt;/foo>
  * </pre>
  *
  *
  *
  *
  * <h2>W3C XML Schema "lax" wildcard emulation</h2>
  * The lax element of the annotation enables the emulation of the "lax" wildcard semantics.
  * For example, when the Java source code is annotated like this:
  * <pre>
  * &#64;{@link XmlRootElement}
  * class Foo {
  *   &#64;XmlAnyElement(lax=true)
  *   public {@link Object}[] others;
  * }
  * </pre>
  * then the following document will unmarshal like this:
  * <pre>
  * &lt;foo>
  *   &lt;unknown />
  *   &lt;foo />
  * &lt;/foo>
  *
  * Foo foo = unmarshal();
  * // 1 for 'unknown', another for 'foo'
  * assert foo.others.length==2;
  * // 'unknown' unmarshals to a DOM element
  * assert foo.others[0] instanceof Element;
  * // because of lax=true, the 'foo' element eagerly
  * // unmarshals to a Foo object.
  * assert foo.others[1] instanceof Foo;
  * </pre>

      * <h3>When false</h3>
      * <p>
      * If false, all the elements that match the property will be unmarshalled
      * to DOM, and the property will only contain DOM elements.
      *
      * <h3>When true</h3>
      * <p>
      * If true, when an element matches a property marked with {@link XmlAnyElement}
      * is known to {@link JAXBContext} (for example, there's a class with
      * {@link XmlRootElement} that has the same tag name, or there's
      * {@link XmlElementDecl} that has the same tag name),
      * the unmarshaller will eagerly unmarshal this element to the JAXB object,
      * instead of unmarshalling it to DOM. Additionally, if the element is
      * unknown but it has a known xsi:type, the unmarshaller eagerly unmarshals
      * the element to a {@link JAXBElement}, with the unknown element name and
      * the JAXBElement value is set to an instance of the JAXB mapping of the
      * known xsi:type.
      *
      * <p>
      * As a result, after the unmarshalling, the property can become heterogeneous;
      * it can have both DOM nodes and some JAXB objects at the same time.
      *
      * <p>
      * This can be used to emulate the "lax" wildcard semantics of the W3C XML Schema.
