/**
 * Data structures used in parsing XML DocBook-based tutorials
 *
 * Conversion of DocBook-based tutorials is performed using special
 * {@link Converter} class methods.  By default, these methods simply retrieve
 * simple rules for replacement of tags and slight re-ordering from the
 * options.ini file present for every template.
 *
 * In future versions, there may be utilization of xslt or other more powerful
 * protocols.  However, for most situations, the power of these classes will
 * be more than sufficient to handle very complex documentation.
 *
 * Note that an entire tutorial is contained in a single parserXMLDocBookTag,
 * matching the document model for DocBook.  The top-level tag, <refentry>,
 * contains every other tag and all text.
