Implementation of W3C Types

This topic provides a correspondence between the DOM classes from the W3C standard and the XML DOM Engine classes from Symbian.

DOM Level 3	Symbian XML DOM Engine	Notes
Node interfaces
`Document`	`RXmlEngDocument`
`Element`	`TXmlEngElement`	Provides an extended set of methods for creating DOM tree contents (child elements, attributes and text).
`Attr`	`TXmlEngAttr`
`Text`	TTextXmlEngNode
`Comment`	`TXmlEngComment`
`EntityReference`	`TXmlEngEntityReference`
`CharacterData`	`TXmlEngCharacterData`	Provides a subset of `CharacterData` modification methods.
`ProcessingInstruction`	`TXmlEngProcessingInstruction`
`CDATASection`	`TXmlEngCDATASection`
`DocumentFragment`	`TXmlEngDocumentFragment`
`DocumentType`		Not supported.
`Entity`		Not supported.
`Notation`		Not supported.
	`TXmlEngNamespace`	Specific to the implementation of the XML DOM Engine.
Basic types
`DOMString`	`TPtrC8`, TString
`DOMObject`	`void*`
`DOMUserData`	`MXmlEngUserData`
`DOMTimeStamp`		Not supported.
Helper interfaces
`NodeList`	`RXmlEngNodeList` `<T>`	Provides iterator-based access instead of the index-based access of the `NodeList` class.
`DOMStringList`		Not supported (only required by the `DOMConfiguration` class, which is not supported either).
`NameList`		Replaced by alternative access mechanisms.
`NamedNodeMap`		Replaced by alternative access mechanisms.
`TypeInfo`		Not supported.
`DOMConfiguration`		Not supported.
`DOMImplementation`	`RXmlEngDOMImplementation`
`UserDataHandler`		Partial support due to limitations of the libxml2 standard library: `IMPORTED`, `RENAMED` and `ADOPTED` operations do not notify `MXmlEngUserData` children.
`DOMError`		Not supported.
`DOMErrorHandler`		Not supported.
`DOMException`		Not supported.
`DOMImplementationList`		Not applicable in the XML DOM Engine.
`DOMLocator`		Not supported by the libxml2 standard library.
	DOMParser	Specific to the implementation of the XML DOM Engine.
