418    [1] In an implementation that supports the
419    [CODE(URI)@en[[[http://suika.fam.cx/www/2006/feature/XDoctype]]]]
420    feature, a [CODE(DOMi)@en[[[DocumentType]]]] node
421    must implement the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]]
422    interface.  See [[DOM XML Document Type Definition]>>3] for
423    details.
424    
425    
426    ** Children
427    
428    [2] The [DFN@en[[CODE(DOMa)@en[[[elementTypes]]]] attribute]]
429    of the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]] interface
430    is a live [CODE(DOMi)@en[[[NamedNodeMap]]]] object that
431    contains all element types belongs to the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]]
432    node.  The type of the attribute is [CODE(DOMi)@en[[[NamedNodeMap]]]].
433    The attribute is read-only.
434    
435    What are contained in this collection depends on how
436    the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]] node was created.  If the
437    node was created as the result of parsing of an XML document,
438    it [['''MUST''']]  contain all element types whose element type and / or
439    attribute definition list declaration are encountered by and provided for the DOM
440    implementation from the XML processor.  Note that the XML processor might not
441    provide a part of or entire such information depending on the configuration.
442    If more than one declarations for an element type or an attribute is available
443    at the time of the definition node construction, then declarations other than
444    the first ones [['''MUST''']] be discarded.
445    
446    The attribute [['''MUST''']] return the [CODE(DOMi)@en[[[NamedNodeMap]]]]
447    object that contains all the [CODE(DOMi)@en[[[ElementTypeDefinition]]]] nodes
448    belong to the node.  The returned [CODE(DOMi)@en[[[NamedNodeMap]]]] object
449    [['''MUST''']] be read-only if and only if the node is read-only.
450    Note that the [CODE(DOMi)@en[[[NamedNodeMap]]]] object is live
451    and therefore any change of read-only flag on the node is immediately
452    reflected by that of the object.
453    
454    [3] The [DFN@en[[CODE(DOMa)@en[[[generalEntities]]]] attribute]]
455    of the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]] interface
456    is a live [CODE(DOMi)@en[[[NamedNodeMap]]]] object that contains all the
457    general entities belong to the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]] node.
458    The type of the attribute is [CODE(DOMi)@en[[[NamedNodeMap]]]].
459    The attribute is read-only.
460    
461    All entities declared in the document type definition
462    contained in or referenced from the document entity
463    might not be exposed through this collection, depending
464    on the information provided by the XML processor for
465    the DOM implementation.  In particular, it might not
466    contain any entity if entity references are expanded
467    at the parse time.  An implementation [['''MUST NOT''']]
468    expose an [CODE(DOMi)@en[[[Entity]]]] node whose [CODE(DOMa)@en[[[nodeName]]]]
469    is equal to the name of one of five predefined general entities in
470    XML through the collection as the result of parsing of an XML
471    document that has no error.  Duplicate entity declarations are also discarded.
472    
473    The attribute [['''MUST''']] return the [CODE(DOMi)@en[[[NamedNodeMap]]]]
474    object that contains all the [CODE(DOMi)@en[[[Entity]]]] nodes
475    representing general entities belong to the node.  The returned
476    [CODE(DOMi)@en[[[NamedNodeMap]]]] object [['''MUST''']] be read-only if and only if
477    the node is read-only. Note that the [CODE(DOMi)@en[[[NamedNodeMap]]]] object is live
478    and therefore any change of read-only flag on the node is immediately
479    reflected by that of the object.
480    
481    The attribute [['''MUST''']] return the same value as the
482    [CODE(DOMa)@en[[[entites]]]] attribute of the
483    [CODE(DOMi)@en[[[DocumentType]]]] interface on the same node.
484    
485    [4] The [DFN@en[[CODE(DOMa)@en[[[notations]]]] attribute]]
486    of the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]] interface
487    is a live [CODE(DOMi)@en[[[NamedNodeMap]]]] object that contains
488    all the notations belong to the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]]
489    node.  The type of the attribute is [CODE(DOMi)@en[[[NamedNodeMap]]]].
490    The attribute is read-only.
491    
492    If the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]] node is
493    created from an XML document, duplicate notation declarations, if any, in DTD
494    [['''MUST NOT''']] result in a node in the [CODE(DOMi)@en[[[NamedNodeMap]]]]
495    object and only the first declaration [['''MUST''']] be
496    made available as a [CODE(DOMi)@en[[[Notation]]]] node.
497    
498    ;; This definition is based on one for the
499    [CODE(DOMa)@en[[[notations]]]] attribute of the
500    [CODE(DOMi)@en[[[DocumentType]]]] interface in DOM XML module.
501    Since duplication is violation to the Validity Constraint,
502    XML parsers might vary on how notations are notified to
503    the application.  In particular, [CODE(InfoProp)@en[[[notations]]]]
504    property of the document information item in XML Information Set
505    is so defined that in case ''any'' notation is declared for
506    multiple times then the property has no value.
507    
508    The attribute [['''MUST''']] return the [CODE(DOMi)@en[[[NamedNodeMap]]]]
509    object that contains all the [CODE(DOMi)@en[[[Notation]]]] nodes
510    representing notations belong to the node.  The returned
511    [CODE(DOMi)@en[[[NamedNodeMap]]]] object [['''MUST''']] be read-only if and only if
512    the node is read-only. Note that the [CODE(DOMi)@en[[[NamedNodeMap]]]] object is live
513    and therefore any change of read-only flag on the node is immediately
514    reflected by that of the object.
515    
516    A DOM implementation is not required to implement the
517    [CODE(DOMa)@en[[[notations]]]] attribute twice
518    for the [CODE(DOMi)@en[[[DocumentType]]]] and
519    the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]] interfaces;
520    the latter is defined to contain the same value as the former.
521    
522    
523    ** Open Issues (informative)
524    
525    [5] A future version of the interface might define the
526    [CODE(DOMa)@en[[[parameterEntities]]]] attribute and
527    getter/setter for parameter entities.
