430    [2] The [DFN@en[[CODE(DOMa)@en[[[elementTypes]]]] attribute]]
431    of the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]] interface
432    is a live [CODE(DOMi)@en[[[NamedNodeMap]]]] object that
433    contains all element types belongs to the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]]
434    node.  The type of the attribute is [CODE(DOMi)@en[[[NamedNodeMap]]]].
435    The attribute is read-only.
436    
437    What are contained in this collection depends on how
438    the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]] node was created.  If the
439    node was created as the result of parsing of an XML document,
440    it [['''MUST''']]  contain all element types whose element type and / or
441    attribute definition list declaration are encountered by and provided for the DOM
442    implementation from the XML processor.  Note that the XML processor might not
443    provide a part of or entire such information depending on the configuration.
444    If more than one declarations for an element type or an attribute is available
445    at the time of the definition node construction, then declarations other than
446    the first ones [['''MUST''']] be discarded.
447    
448    The attribute [['''MUST''']] return the [CODE(DOMi)@en[[[NamedNodeMap]]]]
449    object that contains all the [CODE(DOMi)@en[[[ElementTypeDefinition]]]] nodes
450    belong to the node.  The returned [CODE(DOMi)@en[[[NamedNodeMap]]]] object
451    [['''MUST''']] be read-only if and only if the node is read-only.
452    Note that the [CODE(DOMi)@en[[[NamedNodeMap]]]] object is live
453    and therefore any change of read-only flag on the node is immediately
454    reflected by that of the object.
455    
456    [3] The [DFN@en[[CODE(DOMa)@en[[[generalEntities]]]] attribute]]
457    of the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]] interface
458    is a live [CODE(DOMi)@en[[[NamedNodeMap]]]] object that contains all the
459    general entities belong to the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]] node.
460    The type of the attribute is [CODE(DOMi)@en[[[NamedNodeMap]]]].
461    The attribute is read-only.
462    
463    All entities declared in the document type definition
464    contained in or referenced from the document entity
465    might not be exposed through this collection, depending
466    on the information provided by the XML processor for
467    the DOM implementation.  In particular, it might not
468    contain any entity if entity references are expanded
469    at the parse time.  An implementation [['''MUST NOT''']]
470    expose an [CODE(DOMi)@en[[[Entity]]]] node whose [CODE(DOMa)@en[[[nodeName]]]]
471    is equal to the name of one of five predefined general entities in
472    XML through the collection as the result of parsing of an XML
473    document that has no error.  Duplicate entity declarations are also discarded.
474    
475    The attribute [['''MUST''']] return the [CODE(DOMi)@en[[[NamedNodeMap]]]]
476    object that contains all the [CODE(DOMi)@en[[[Entity]]]] nodes
477    representing general entities belong to the node.  The returned
478    [CODE(DOMi)@en[[[NamedNodeMap]]]] object [['''MUST''']] be read-only if and only if
479    the node is read-only. Note that the [CODE(DOMi)@en[[[NamedNodeMap]]]] object is live
480    and therefore any change of read-only flag on the node is immediately
481    reflected by that of the object.
482    
483    The attribute [['''MUST''']] return the same value as the
484    [CODE(DOMa)@en[[[entites]]]] attribute of the
485    [CODE(DOMi)@en[[[DocumentType]]]] interface on the same node.
486    
487    [4] The [DFN@en[[CODE(DOMa)@en[[[notations]]]] attribute]]
488    of the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]] interface
489    is a live [CODE(DOMi)@en[[[NamedNodeMap]]]] object that contains
490    all the notations belong to the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]]
491    node.  The type of the attribute is [CODE(DOMi)@en[[[NamedNodeMap]]]].
492    The attribute is read-only.
493    
494    If the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]] node is
495    created from an XML document, duplicate notation declarations, if any, in DTD
496    [['''MUST NOT''']] result in a node in the [CODE(DOMi)@en[[[NamedNodeMap]]]]
497    object and only the first declaration [['''MUST''']] be
498    made available as a [CODE(DOMi)@en[[[Notation]]]] node.
499    
500    ;; This definition is based on one for the
501    [CODE(DOMa)@en[[[notations]]]] attribute of the
502    [CODE(DOMi)@en[[[DocumentType]]]] interface in DOM XML module.
503    Since duplication is violation to the Validity Constraint,
504    XML parsers might vary on how notations are notified to
505    the application.  In particular, [CODE(InfoProp)@en[[[notations]]]]
506    property of the document information item in XML Information Set
507    is so defined that in case ''any'' notation is declared for
508    multiple times then the property has no value.
509    
510    The attribute [['''MUST''']] return the [CODE(DOMi)@en[[[NamedNodeMap]]]]
511    object that contains all the [CODE(DOMi)@en[[[Notation]]]] nodes
512    representing notations belong to the node.  The returned
513    [CODE(DOMi)@en[[[NamedNodeMap]]]] object [['''MUST''']] be read-only if and only if
514    the node is read-only. Note that the [CODE(DOMi)@en[[[NamedNodeMap]]]] object is live
515    and therefore any change of read-only flag on the node is immediately
516    reflected by that of the object.
517    
518    A DOM implementation is not required to implement the
519    [CODE(DOMa)@en[[[notations]]]] attribute twice
520    for the [CODE(DOMi)@en[[[DocumentType]]]] and
521    the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]] interfaces;
522    the latter is defined to contain the same value as the former.
523    
524    
525    ** Open Issues (informative)
526    
527    [5] A future version of the interface might define the
