DOM Document Type Definition Module

Feature Name

In a DOM implementation that supports the version 3.0 of the DOM Document Type Definition module, the hasFeature method of a DOMImplementation object MUST return true when the parameters are set to http://suika.fam.cx/www/2006/feature/XDoctype and 3.0 respectively.

In such an implementation, the getFeature method of a Document object MUST return the (at least conceptually) same object implementing the DocumentXDoctype interface when the parameters are set to http://suika.fam.cx/www/2006/feature/XDoctype and 3.0 respectively. Likewise, any method that takes one or more feature names with or without version number, including the methods hasFeature and getFeature, MUST behave in a manner consistent with the aforementioned cases.

[1] In an implementation that supports the 
[CODE(URI)@en[[[http://suika.fam.cx/www/2006/feature/XDoctype]]]]
feature, a [CODE(DOMi)@en[[[DocumentType]]]] node
must implement the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]]
interface.  See [[DOM XML Document Type Definition]>>3] for
details.

elementTypes of type NamedNodeMap, read‐only

A live NamedNodeMap object that contains all the element type definitions belonging to the DocumentType node.

On getting, the attribute MUST return the NamedNodeMap object that contains all the ElementTypeDefinition nodes belonging to the DocumentType node. The NamedNodeMap object MUST be read‐only if and only if the node is read‐only. The NamedNodeMap object MUST be live and the same object MUST be returned for any invocation.

If the DocumentType node is created during the process to create a DOM from an XML document, the following requirements are applied: The NamedNodeMap object in the elementType attribute MUST be so transformed that the object contains the ElementTypeDefinition nodes for the element types whose name is presented as the Name of the element type or attribute definition list declarations processed by the XML processor. If there is more than one element type declarations for an element type, then the declarations other than the first one MUST be ignored for the purpose of constructing the NamedNodeMap object.

generalEntities of type NamedNodeMap, read‐only

A live NamedNodeMap object that contains all the general entities belonging to the DocumentType node.

On getting, the attribute MUST return the same value as the entities attribute (defined in the DocumentType interface) of the same node.

This attribute is part of the interface for historical reason.

notations of type notations, read‐only

A live NamedNodeMap object that contains all the notations belonging to the DocumentType node.

On getting, the attribute MUST return the same value as the notations attribute (defined in the DocumentType interface) of the same node.

This attribute is part of the interface for historical reason.

Implementations are not required to implement the notations attribute twice (for DocumentType and DocumentTypeDefinition interfaces); they share exactly same definition.

ownerElementTypeDefinition of type ElementTypeDefinition, read‐only

The ElementTypeDefinition to which the AttributeDefinition node belongs.

On getting, the attribute MUST return an ElementTypeDefinition node. It MUST be such a node that whose attributeDefinitions attribute contains the NamedNodeMap object that contains the AttributeDefinition node. If there is no such an ElementTypeDefinition node, then null MUST be returned.

declaredType of type unsigned short

The declared type @@ ref of the attribute. It is expected that this attribute contains a value from the definition group DeclaredValueType.

On getting, the attribute MUST return the value associated to this attribute.

On setting, the attribute MUST raise a NO_MODIFICATION_ALLOWED_ERR @@ ref exception if the AttributeDefinition node is read‐only @@ ref. Otherwise, it MUST set the specified value as the value associated to this attribute.

If the AttributeDefinition node is created during the process to create a DOM from an XML document, an appropriate value from the DeclaredValueType constant group MUST be set to the attribute.

The definition group DeclaredValueType contains integers indicating the declared type of attributes. The definition group contains the following constants:

Name	Value	Description
NO_TYPE_ATTR	0	No value [INFOSET].
CDATA_ATTR	1	CDATA [XML].
ID_ATTR	2	ID [XML].
IDREF_ATTR	3	IDREF [XML].
IDREFS_ATTR	4	IDREFS [XML].
ENTITY_ATTR	5	ENTITY [XML].
ENTITIES_ATTR	6	ENTITIES [XML].
NMTOKEN_ATTR	7	NMTOKEN [XML].
NMTOKENS_ATTR	8	NMTOKENS [XML].
NOTATION_ATTR	9	NOTATION [XML].
ENUMERATION_ATTR	10	Enumeration [XML].
UNKNOWN_ATTR	11	Unknown, because no declaration for the attribute has been read but the [all declaration processed] property [INFOSET] would be false.

If no attribute type information is available, or if the source of the information does not distinguish no value and unknown [INFOSET], then the value NO_TYPE_ATTR MUST be used.

An AttributeDefinition node created by the createAttributeDefinition method has its declaredType attribute set to NO_TYPE_ATTR.

If the source of the information does not distinguish no value and/or unknown [INFOSET] and CDATA [XML], then the value CDATA_ATTR MUST be used.

In Perl binding [PERLBINDING], the Attr nodes MUST implement the DeclaredValueType definition group.

defaultType of type unsigned short

The type of the default for the attribute. It is expected that this attribute contains a value from the definition group DefaultValueType.

On getting, the attribute MUST return the value associated to this attribute.

On setting, the attribute MUST raise a NO_MODIFICATION_ALLOWED_ERR @@ ref exception if the AttributeDefinition node is read‐only @@ ref. Otherwise, it MUST set the specified value as the value associated to this attribute.

If the AttributeDefinition node is created during the process to create a DOM from an XML document, an appropriate value from the DefaultValueType definition group MUST be set to the attribute.

The definition group DefaultValueType contains integers indicating the type of the default for the attribute. The definition group contains the following constans:

Name	Value	Description
UNKNOWN_DEFAULT	0	Unknown.
FIXED_DEFAULT	1	Provided explicitly and fixed @@ ref to that value.
REQUIRED_DEFAULT	2	No default value and the attribute have to be explicitly specified.
IMPLIED_DEFAULT	3	Implied @@ ref.
EXPLICIT_DEFAULT	4	Provided explicitly.

If the source of the default type does not distinguish implied and unknown default types, then the value IMPLIED_DEFAULT MUST be used.

An AttributeDefinition node created by the createAttributeDefinition method has its defaultType attribute set to UNKNOWN_DEFAULT.

Modifications to the DocumentType Interface

A DocumentType interface MAY contain zero or more ProcessingInstruction nodes in the NodeList object contained in the childNodes attribute of the DocumentType node.

If the DocumentType node is created during the process to create a DOM from an XML document, the NodeList object in the childNodes object MUST contains the ProcessingInstruction nodes representing the processing instructions in the document type definition of the document processed @@ ref by the XML processor. If the DocumentType node is marked as read‐only, then all the child nodes MUST also be marked as read‐only.

If a DocumentType node is created from a document type declaration information item @@ ref, the NodeList object in the childNodes attribute of the node MUST contain the ProcessingInstruction nodes created from the processing instruction information items in the list in the [children] property of the document type declaration item in the same order.

If a DocumentType node is mapped to a document type declaration information item, the list in the [children] property MUST contain the processng instruction information items created from the ProcessingInstruction nodes in the NodeList object in the childNodes attribute of the DocumentType node.

// Modifications to the DocumentType interface
  attribute DOMString publicId;
  attribute DOMString systemId;

The publicId attribute and the systemId attribute of DocumentType, Entity, and Notation objects are now read-write. 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. 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. 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. ISSUE: In HTML5, Firefox 1.5, and Opera 9, not specifying public or system identifier results in empty strings.
