  49 /*  An CFXMLNode describes an individual XML construct - like a tag, or a comment, or a string
  50     of character data.  Each CFXMLNode contains 3 main pieces of information - the node's type,
  51     the data string, and a pointer to an additional data structure.  The node's type ID is an enum
  52     value of type CFXMLNodeTypeID.  The data string is always a CFStringRef; the meaning of the
  53     string is dependent on the node's type ID. The format of the additional data is also dependent
  54     on the node's type; in general, there is a custom structure for each type that requires
  55     additional data.  See below for the mapping from type ID to meaning of the data string and
  56     structure of the additional data.  Note that these structures are versioned, and may change
  57     as the parser changes.  The current version can always be identified by kCFXMLNodeCurrentVersion;
  58     earlier versions can be identified and used by passing earlier values for the version number
  59     (although the older structures would have been removed from the header).
  60
  61     An CFXMLTree is simply a CFTree whose context data is known to be an CFXMLNodeRef.  As
  62     such, an CFXMLTree can be used to represent an entire XML document; the CFTree
  63     provides the tree structure of the document, while the CFXMLNodes identify and describe
  64     the nodes of the tree.  An XML document can be parsed to a CFXMLTree, and a CFXMLTree
  65     can generate the data for the equivalent XML document - see CFXMLParser.h for more
  66     information on parsing XML.
