The /// well-formed writer performs many checks in behalf of the raw writer, and keeps state that the /// raw writer otherwise would have to keep. Therefore, the well-formed writer will call the /// XmlRawWriter using the following rules, in order to make raw writers easier to implement: /// /// 1. The well-formed writer keeps a stack of element names, and always calls /// WriteEndElement(string, string, string) instead of WriteEndElement(). /// 2. The well-formed writer tracks namespaces, and will pass himself in via the /// WellformedWriter property. It is used in the XmlRawWriter's implementation of IXmlNamespaceResolver. /// Thus, LookupPrefix does not have to be implemented. /// 3. The well-formed writer tracks write states, so the raw writer doesn't need to. /// 4. The well-formed writer will always call StartElementContent. /// 5. The well-formed writer will always call WriteNamespaceDeclaration for namespace nodes, /// rather than calling WriteStartAttribute(). /// 6. The well-formed writer guarantees a well-formed document, including correct call sequences, /// correct namespaces, and correct document rule enforcement. /// 7. All element and attribute names will be fully resolved and validated. Null will never be /// passed for any of the name parts. /// 8. The well-formed writer keeps track of xml:space and xml:lang. /// 9.
