/**
 * The <code>Property</code> class represents a Property of a WebDAV
 * resource. The {@link #hashCode()} and {@link #equals(Object)} METHODS are
 * overridden in a way, that the name and value of the property are
 * respected. this means, an property is equal to another, if the names
 * and values are equal.<br>
 * The XML representation of a <code>DavProperty</code>:
 * <pre>
 * new DavProperty("displayname", "WebDAV Directory").toXml
 * gives a element like:
 * &lt;D:displayname&gt;WebDAV Directory&lt;/D:displayname&gt;
 *
 * new DavProperty("resourcetype", new Element("collection")).toXml
 * gives a element like:
 * &lt;D:resourcetype&gt;&lt;D:collection/&gt;&lt;/D:resourcetype&gt;
 *
 * Element[] customVals = { new Element("bla", customNamespace), new Element("bli", customNamespace) };
 * new DavProperty("custom-property", customVals, customNamespace).toXml
 * gives an element like
