nodeinsertbefore14
IBM
The method insertBefore inserts the node newChild before the existing child node refChild.
If refChild is null, insert newChild at the end of the list of children.
A NO_MODIFICATION_ALLOWED_ERR is raised if the node is read-only.
Using insertBefore on this Document node attempt to insert a new Attr node before
this DocumentType node and verfiy if a NO_MODIFICATION_ALLOWED_ERR is raised.
(This can also raise a HIERARCHY_REQUEST_ERR and NOT_FOUND_ERR)
