+ * The classes that make up a meta entity are:
+ * <dl>
+ *   <dt>SwTextMeta</dt><dd>the text hint</dd>
+ *   <dt>SwFormatMeta</dt><dd>the pool item</dd>
+ *   <dt>sw::Meta</dt><dd>the metadatable entity itself</dd>
+ *   <dt>SwXMeta</dt><dd>the UNO wrapper object</dd>
+ * </dl>
+ *
+ * The text hint contains the pool item (as usual) and has a pointer to the
+ * text node at which it is attached.
+ * The pool item has a shared pointer to the metadatable entity, and a reverse
+ * pointer to the text attribute at which it is attached.
+ * The pool item is non-poolable; it may only be attached to one text
+ * attribute.
+ * Of all the pool items that refer to a metadatable entity, only one may be
+ * in the document content at any time. Others may be in the undo array, or in
+ * undo objects.
+ * The metadatable entity has a reverse pointer to the pool item that is
+ * currently in the document. It also registers as a client at the text node
+ * at which it is attached via this pool item and its text attribute.
+ * The UNO wrapper object registers as a client at the metadatable entity.
+ *
+ * Copying the metadatable entity proceeds in the following way:
+ * <ol>
+ *   <li>The pool item is cloned (because it is non-poolable); the clone
+ *       points to the same metadatable entity, but the metadatable entity's
+ *       reverse pointer is unchanged.</li>
+ *   <li>The DoCopy() method is called at the new pool item:
+ *       it will clone the metadatable entity (using RegisterAsCopyOf).
+ *       This is necessary, because first, a metadatable entity may
+ *       only be inserted once into a document, and second, the copy may be
+ *       inserted into a different document than the source document!</li>
+ *   <li>A new text hint is created, taking over the new pool item.</li>
+ *   <li>The text hint is inserted into the hints array of some text node.</li>
+ * </ol>
