 * The fragment sink allows a client to parse a fragment of sink, possibly
 * surrounded in context. Also see nsIParser::ParseFragment().
 * Note: once you've parsed a fragment, the fragment sink must be re-set on
 * the parser in order to parse another fragment.
class nsIFragmentContentSink : public nsISupports {
   * This method is used to obtain the fragment created by
   * a fragment content sink. The value returned will be null
   * if the content sink hasn't yet received parser notifications.
   * If aWillOwnFragment is PR_TRUE then the sink should drop its
   * ownership of the fragment.
  NS_IMETHOD GetFragment(PRBool aWillOwnFragment,
                         nsIDOMDocumentFragment** aFragment) = 0;

   * This method is used to set the target document for this fragment
   * sink.  This document's nodeinfo manager will be used to create
   * the content objects.  This MUST be called before the sink is used.
   * @param aDocument the document the new nodes will belong to
   * (should not be null)
  NS_IMETHOD SetTargetDocument(nsIDocument* aDocument) = 0;

   * This method is used to indicate to the sink that we're done building
   * the context and should start paying attention to the incoming content
  NS_IMETHOD WillBuildContent() = 0;

   * This method is used to indicate to the sink that we're done building
   * The real content. This is useful if you want to parse additional context
   * (such as an end context).
  NS_IMETHOD DidBuildContent() = 0;

   * This method is a total hack to help with parsing fragments. It is called to
   * tell the fragment sink that a container from the context will be delivered
   * after the call to WillBuildContent(). This is only relevent for HTML
   * fragments that use nsHTMLTokenizer/CNavDTD.
  NS_IMETHOD IgnoreFirstContainer() = 0;


 * Base version takes string nested in context, content surrounded by
 * WillBuildContent()/DidBuildContent() calls. The 2nd version just loads
 * the whole string.
