/**
 * Class representing SAML 2 EndpointType.
 *
 * This class can be used in two different ways:
 *
 *   - You can extend the class without extending the constructor. Then you can use the methods available and the class
 *     will generate an element with the same name as the extending class
 *     (e.g. \SimpleSAML\SAML2\XML\md\AttributeService).
 *
 *   - Alternatively, you may want to extend the type to add new attributes (e.g look at IndexedEndpointType). In that
 *     case, you cannot use this class normally, as if you change the signature of the constructor, you cannot call
 *     fromXML() in this class. In order to process an XML document, you can use the get*Attribute() static methods
 *     from AbstractElement, and reimplement the fromXML() method with them to suit your new constructor.
