/**
* 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>
