/**
 * Initialize the SWCL WebdavResource.// ww  w  . j  a  va 2 s .c o m

 * The action argument specifies a set of properties to load during initialization.
 * Its value is one of WebdavResource.NOACTION, WebdavResource.NAME,
 * WebdavResource.BASIC, WebdavResource.DEFAULT, WebdavResource.ALL.
 * Similarly the depth argument specifies the depth header of the PROPFIND
 * method that is executed upon initialization.
 * </p>
 * <p>
 * The different methods of this Source implementation call this method to
 * initialize the resource using their minimal action and depth requirements.
 * For instance the WebDAVSource.getMimeType() method requires WebdavResource.BASIC
 * properties and a search depth of 0 is sufficient.
 * </p>
 * <p>
 * However it may be that a later call (eg. WebDAVSource.getChildren()) requires more
 * information. In that case the WebdavResource would have to make another call to the Server.
 * It would be more efficient if previous initialization had been done using depth 1 instead.
 * In order give the user more control over this the WebDAVSource can be passed a minimal
 * action and depth using cocoon:webdav-depth and cocoon:webdav-action query string parameters.
 * By default the mimimum action is WebdavResource.BASIC (which loads all the following basic
 * webdav properties: DAV:displayname, DAV:getcontentlength, DAV:getcontenttype DAV:resourcetype,
 * DAV:getlastmodified and DAV:lockdiscovery). The default minimum depth is 1.
