* Content nodes in the document tree must <B>not</B> be manipulated directly.

|
* Content nodes in document fragments that are not part of the document itself
|
|
* may be manipulated at will. Operations on document fragments must <B>not</B>
|
|
* go through the editor.
|
|
* 2. Selection must not be explicitly set by the rule method.
|
|
* Any manipulation of Selection must be done by the editor.
