893     The publicId attribute and the systemId attribute of DocumentType, Entity, and Notation objects are now read-write.
894    
895    The setter MUST throw a NO_MODIFICATION_ALLOWED_ERR DOMException if the Node object is read-only. Otherwise, it MUST set the specified value to the attribute. No normalization, lexical validation, or relative reference resolving is performed. null, which represents no public or system identifier is provided, might be specified.
896    
897    Setting public or system identifier does never result in any lexical or logical structure of the document being changed. In particular, no external entity referenced by new identifier will be loaded.
898    
899    Setting an invalid or non-normalized identifier might make the object non-serializable. Setting a non-null public identifier to a DocumentType or Entity object that does not have non-null system identifier or setting null as the system identifier of a DocumentType or Entity object that does have non-null public identifier will make that object non-serializable.

901    ISSUE: In HTML5, Firefox 1.5, and Opera 9, not specifying public or system identifier results in empty strings.

 Otherwise, the setter [['''MUST''']] set the specified
