This is a work-in-progress specification for DOM Document Type Definition module, as implemented by manakai and partially documented in the SuikaWiki.

Interfaces defined in this specification are partially modeled from early drafts of DOM level 1 @@ ref, DOM Abstract Schema level 3 @@ ref, and XML Schema API, but are not compatible with any of them as a whole.

@@ ref to DOM Binding Spec
The DOM Document Type Definition module, version 3.0, consists of three interfaces:
In addition, it adds methods, attributes, and/or constants to interfaces
Node,
Entity,
EntityReference, and
Notation.
It modifies semantics of some of methods and attributes in
Node and
ProcessingInstruction
interfaces, for the support of new interfaces.
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.

DocumentTypeDefinition Interfaceinterface DocumentTypeDefinition {
}[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. ** Children [2] The [DFN@en[[CODE(DOMa)@en[[[elementTypes]]]] attribute]] of the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]] interface is a live [CODE(DOMi)@en[[[NamedNodeMap]]]] object that contains all element types belongs to the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]] node. The type of the attribute is [CODE(DOMi)@en[[[NamedNodeMap]]]]. The attribute is read-only. What are contained in this collection depends on how the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]] node was created. If the node was created as the result of parsing of an XML document, it [['''MUST''']] contain all element types whose element type and / or attribute definition list declaration are encountered by and provided for the DOM implementation from the XML processor. Note that the XML processor might not provide a part of or entire such information depending on the configuration. If more than one declarations for an element type or an attribute is available at the time of the definition node construction, then declarations other than the first ones [['''MUST''']] be discarded. The attribute [['''MUST''']] return the [CODE(DOMi)@en[[[NamedNodeMap]]]] object that contains all the [CODE(DOMi)@en[[[ElementTypeDefinition]]]] nodes belong to the node. The returned [CODE(DOMi)@en[[[NamedNodeMap]]]] object [['''MUST''']] be read-only if and only if the node is read-only. Note that the [CODE(DOMi)@en[[[NamedNodeMap]]]] object is live and therefore any change of read-only flag on the node is immediately reflected by that of the object. [3] The [DFN@en[[CODE(DOMa)@en[[[generalEntities]]]] attribute]] of the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]] interface is a live [CODE(DOMi)@en[[[NamedNodeMap]]]] object that contains all the general entities belong to the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]] node. The type of the attribute is [CODE(DOMi)@en[[[NamedNodeMap]]]]. The attribute is read-only. All entities declared in the document type definition contained in or referenced from the document entity might not be exposed through this collection, depending on the information provided by the XML processor for the DOM implementation. In particular, it might not contain any entity if entity references are expanded at the parse time. An implementation [['''MUST NOT''']] expose an [CODE(DOMi)@en[[[Entity]]]] node whose [CODE(DOMa)@en[[[nodeName]]]] is equal to the name of one of five predefined general entities in XML through the collection as the result of parsing of an XML document that has no error. Duplicate entity declarations are also discarded. The attribute [['''MUST''']] return the [CODE(DOMi)@en[[[NamedNodeMap]]]] object that contains all the [CODE(DOMi)@en[[[Entity]]]] nodes representing general entities belong to the node. The returned [CODE(DOMi)@en[[[NamedNodeMap]]]] object [['''MUST''']] be read-only if and only if the node is read-only. Note that the [CODE(DOMi)@en[[[NamedNodeMap]]]] object is live and therefore any change of read-only flag on the node is immediately reflected by that of the object. The attribute [['''MUST''']] return the same value as the [CODE(DOMa)@en[[[entites]]]] attribute of the [CODE(DOMi)@en[[[DocumentType]]]] interface on the same node. [4] The [DFN@en[[CODE(DOMa)@en[[[notations]]]] attribute]] of the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]] interface is a live [CODE(DOMi)@en[[[NamedNodeMap]]]] object that contains all the notations belong to the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]] node. The type of the attribute is [CODE(DOMi)@en[[[NamedNodeMap]]]]. The attribute is read-only. If the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]] node is created from an XML document, duplicate notation declarations, if any, in DTD [['''MUST NOT''']] result in a node in the [CODE(DOMi)@en[[[NamedNodeMap]]]] object and only the first declaration [['''MUST''']] be made available as a [CODE(DOMi)@en[[[Notation]]]] node. ;; This definition is based on one for the [CODE(DOMa)@en[[[notations]]]] attribute of the [CODE(DOMi)@en[[[DocumentType]]]] interface in DOM XML module. Since duplication is violation to the Validity Constraint, XML parsers might vary on how notations are notified to the application. In particular, [CODE(InfoProp)@en[[[notations]]]] property of the document information item in XML Information Set is so defined that in case ''any'' notation is declared for multiple times then the property has no value. The attribute [['''MUST''']] return the [CODE(DOMi)@en[[[NamedNodeMap]]]] object that contains all the [CODE(DOMi)@en[[[Notation]]]] nodes representing notations belong to the node. The returned [CODE(DOMi)@en[[[NamedNodeMap]]]] object [['''MUST''']] be read-only if and only if the node is read-only. Note that the [CODE(DOMi)@en[[[NamedNodeMap]]]] object is live and therefore any change of read-only flag on the node is immediately reflected by that of the object. A DOM implementation is not required to implement the [CODE(DOMa)@en[[[notations]]]] attribute twice for the [CODE(DOMi)@en[[[DocumentType]]]] and the [CODE(DOMi)@en[[[DocumentTypeDefinition]]]] interfaces; the latter is defined to contain the same value as the former. ** Open Issues (informative) [5] A future version of the interface might define the [CODE(DOMa)@en[[[parameterEntities]]]] attribute and getter/setter for parameter entities.
