Curt Arnold The "setData(data)" method for a processing instruction causes the DOMException NO_MODIFICATION_ALLOWED_ERR to be raised if the node is readonly. Create an ent4 entity reference and add to document of the THIRD "gender" element. The elements content is an entity reference. Try to remove the "domestic" attribute from the entity reference by executing the "setData(data)" method. This causes a NO_MODIFICATION_ALLOWED_ERR DOMException to be thrown. 2001-08-21
