/**
* Provides an HTTP REST interface for the management of an XML based metadata document.
* <p/>
* The URL pattern for this end-point is:<br/>
* <i>http://host:port/application/</i><b>rest&#47;manage&#47;document</b>
* <p/>
* Four HTTP methods are supported:
* <ul>
*   <li>GET - gets an XML document from the catalog
*     <ul>
*       <li>the subject document must be specified within the URL</li>
*       <li>the XML is returned within the body of the HTTP response</li>
*     </ul>
*   <li>PUT - publishes an XML document to the catalog
*     <ul>
*       <li>the XML must be supplied within the body of the HTTP request.</li>
*       <li>URL parameter publicationMethod is accepted, values are upload,editor,other</li>
*       <li>URL parameter asDraft=true is accepted</li>
*       <li>if no document provided, that means this is resource registration request.</li>
*       <li>returns HTTP 200 when a document is replaced</li>
*       <li>returns HTTP 201 when a document is created</li>
*     </ul>
*   <li>POST - same as PUT</li>
*   <li>DELETE - deletes a document from the catalog
*     <ul>
*       <li>the subject document must be specified within the URL</li>
*       <li>returns HTTP 200 when a document is deleted</li>
*     </ul>
* </ul>
* The subject document can be specified within the URL as follows:
* <ul>
*   <li>.../rest/manage/document/<b>identifier</b></li>
*   <li>.../rest/manage/document<b>?id=identifier</b></li>
*   <li><b>identifier</b> can be the catalog's UUID for the document,
*         or the file identifier internal to the XML document</li>
*   <li><b>identifier</b> must be properly URL encoded</li>
* </ul>
* Attributes applicable for resource registration:
* <ul>
*    <li>url - resource URL (required)</li>
*    <li>uuid - UUID of the resource (optional). If provided this is an update of the already existing resource</li>
*    <li>name - resource name/title (optional)</li>
*    <li>protocol - protocol type (optional: res,arcgis,arcims,csw,oai,waf). Default: res</li>
*    <li>frequency - frequency (optional: Monthly, BiWeekly, Weekly, Dayly, Hourly, Once, Skip). Default: Skip</li>
*    <li>sendNotification - to send notification (optional: true,false). Default: false</li>
*    <li>updateContent - to harvest content during synchronization (optional: true,false). Default: true</li>
*    <li>updateDefinition - to update definition during synchronization (optional: true,false). Default: true</li>
*    <li>autoApprove - to automatically approve newly acquired metadata (optional: true,false). Default: true</li>
*    <li>findable - to make this resource findable when searching for metadata (optional: true, false), Default: true</li>
*    <li>searchable - to make this resource to act as distributed search endpoint (only if csw) (optional: true, false), Default: true</li>
*    <li>synchronizable - to make this resource synchronizable (optional: true, false), Default: true</li>
*    <li>username - user name required to access protected resource (optional)</li>
*    <li>password - password required to access protected resource (optional)</li>
*    <li>soapurl - (ARCGIS only) resource SOAP URL</li>
*    <li>profile - (CSW only) profile</li>
*    <li>set - (OAI only) set</li>
*    <li>prefix - (OAI only) prefix</li>
*    <li>service - (ARCIMS only) service</li>
*    <li>port - (ARCIMS only) port</li>
*    <li>rootFolder - (ARCIMS only) root folder</li>
* </ul>
* Exceptions applicable to all methods:
* <ul>
*   <li>HTTP 401 Unauthorized
*       - indicates that valid credentials must be supplied to access this URL</li>
*   <li>HTTP 403 The document is owned by another user.
*       - when an attempt is made to access a document owned by another user</li>
* </ul>
* Exceptions applicable to GET/DETETE:
* <ul>
*   <li>HTTP 404 Document not found..
*       - when the document specified within the request URL could not be located
*         within the catalog</li>
* </ul>
* Exceptions applicable to PUT/POST:
* <ul>
*   <li>HTTP 400 IOException while reading request body.
*       - when characters could not be read from the request body</li>
*   <li>HTTP 409 Document was empty.
*       - when the request body was empty</li>  
*   <li>HTTP 409 Unable to parse document as XML.
*       - when the content of the request body cannot be parsed as XML</li>
*   <li>HTTP 409 Unrecognized metadata schema.
*       - when the supplied XML does not match a configured XML standard for the catalog</li>
*   <li>HTTP 409 Document failed to validate..
*       - when the supplied XML is invalid with respect to the configured validation rules
*         for the catalog</li>
*   <li>HTTP 409 XSD violation.
*       - when the supplied XML is invalid with respect to it's XSD</li>
*   <li>HTTP 409 Duplicated resource URL.
