 * the document's state when loaded, and the %XML tree, which contains all
 * information about the document's %XML representation. For this reason
 * this tree is also called the "repr tree", and %XML nodes are called "reprs".
 *
 * The central class is XML::Node, which provides all operations. It should be
 * noted that nodes are currently typeless and operations not valid for their
 * type simply do nothing (like trying to iterate over children of a text node).
 * In addition to standard DOM operations, the %XML tree supports observers -
 * objects derived from Xml::NodeObserver which receive notifications about
 * changes in the document tree.

/** \mainpage Inkscape Source Code Documentation
 * While the standard doxygen documentation can be accessed through the links
 * in the header, the following documents are additionally available to the
 * interested reader.
 *
 * \section groups Main directory documentation
 * Inkscape's classes and files in the main directory can be grouped into
 * the following categories:
 *
 * - \subpage ObjectTree - inkscape's SVG canvas
 * - \subpage Tools - the tools UI
 * - \subpage UI - inkscape's user interface
 * - \subpage XmlTree - XML backbone of the document
 * - \subpage Rendering - rendering and buffering
 * - \subpage OtherServices - what doesn't fit in the above
 *
 * See also the <a href="dirs.html">other directories</a> until doxygen
 * allows setting links to those doc files.
