Function DOMImplementation.Node.readonly

The DOM specification defines a readonly node as "a node that is immutable. This means its list of children, its content, and its attributes, when it is an element, cannot be changed in any way. However, a read only node can possibly be moved, when it is not itself contained in a read only node."

For example, Notations, EntityReferences and all of theirs descendants are always readonly.
