+Summary: Reduce the size of XML objects
+
+Right now, when we load large xml documents using XmlDocument, we take up
+too much memory.
+
+The problem is that our classes are somewhat bloated:
+
+[benm@omega benm]$ mono foo.exe
+Fields of System.Xml.XmlNode
+     ownerDocument -- System.Xml.XmlDocument (Object)
+     parentNode -- System.Xml.XmlNode (Object)
+     lastLinkedChild -- System.Xml.XmlLinkedNode (Object)
+     childNodes -- System.Xml.XmlNodeListChildren (Object)
+     isReadOnly -- System.Boolean (Boolean)
+Fields of System.Xml.XmlElement
+     attributes -- System.Xml.XmlAttributeCollection (Object)
+     localName -- System.String (String)
+     namespaceURI -- System.String (String)
+     prefix -- System.String (String)
+     isNotEmpty -- System.Boolean (Boolean)
+     nextSibling -- System.Xml.XmlLinkedNode (Object)
+     ownerDocument -- System.Xml.XmlDocument (Object)
+     parentNode -- System.Xml.XmlNode (Object)
+     lastLinkedChild -- System.Xml.XmlLinkedNode (Object)
+     childNodes -- System.Xml.XmlNodeListChildren (Object)
+     isReadOnly -- System.Boolean (Boolean)
+Fields of System.Xml.XmlAttribute
+     localName -- System.String (String)
+     namespaceURI -- System.String (String)
+     prefix -- System.String (String)
+     isDefault -- System.Boolean (Boolean)
+     ownerElement -- System.Xml.XmlElement (Object)
+     ownerDocument -- System.Xml.XmlDocument (Object)
+     parentNode -- System.Xml.XmlNode (Object)
+     lastLinkedChild -- System.Xml.XmlLinkedNode (Object)
+     childNodes -- System.Xml.XmlNodeListChildren (Object)
+     isReadOnly -- System.Boolean (Boolean)
+Fields of System.Xml.XmlText
+     data -- System.String (String)
+     nextSibling -- System.Xml.XmlLinkedNode (Object)
+     ownerDocument -- System.Xml.XmlDocument (Object)
+     parentNode -- System.Xml.XmlNode (Object)
+     lastLinkedChild -- System.Xml.XmlLinkedNode (Object)
+     childNodes -- System.Xml.XmlNodeListChildren (Object)
+     isReadOnly -- System.Boolean (Boolean)
+
+
+On msft, I get:
+
+
+C:\Inetpub\ftproot>foo
+Fields of System.Xml.XmlNode
+     parentNode -- System.Xml.XmlNode (Object)
+Fields of System.Xml.XmlElement
+     name -- System.Xml.XmlName (Object)
+     attributes -- System.Xml.XmlAttributeCollection (Object)
+     lastChild -- System.Xml.XmlLinkedNode (Object)
+     next -- System.Xml.XmlLinkedNode (Object)
+     parentNode -- System.Xml.XmlNode (Object)
+Fields of System.Xml.XmlAttribute
+     name -- System.Xml.XmlName (Object)
+     lastChild -- System.Xml.XmlLinkedNode (Object)
+     parentNode -- System.Xml.XmlNode (Object)
+Fields of System.Xml.XmlText
+     next -- System.Xml.XmlLinkedNode (Object)
+     parentNode -- System.Xml.XmlNode (Object)
+
+Note how msft has *many* fewer fields. This reduces the size of the
+document in memory.
