+ * @Title: Simple XML Subset Parser * @Short_description: parses a subset of XML
+ * @See_also: [XML Specification](http://www.w3.org/TR/REC-xml/)
+ *
+ * The "GMarkup" parser is intended to parse a simple markup format
+ * that's a subset of XML. This is a small, efficient, easy-to-use
+ * parser. It should not be used if you expect to interoperate with
+ * other applications generating full-scale XML. However, it's very
+ * useful for application data files, config files, etc. where you
+ * know your application will be the only one writing the file.
+ * Full-scale XML parsers should be able to parse the subset used by
+ * GMarkup, so you can easily migrate to full-scale XML at a later
+ * time if the need arises.
+ *
+ * GMarkup is not guaranteed to signal an error on all invalid XML;
+ * the parser may accept documents that an XML parser would not.
+ * However, XML documents which are not well-formed (which is a
+ * weaker condition than being valid. See the
+ * [XML specification](http://www.w3.org/TR/REC-xml/)
+ * for definitions of these terms.) are not considered valid GMarkup
+ * documents.
+ *
+ * Simplifications to XML include:
+ *
+ * - Only UTF-8 encoding is allowed
+ *
+ * - No user-defined entities
+ *
+ * - Processing instructions, comments and the doctype declaration
+ * are "passed through" but are not interpreted in any way
+ *
+ * - No DTD or validation
+ *
+ * The markup format does support:
+ *
+ * - Elements
+ *
+ * - Attributes
+ *
+ * - 5 standard entities: & < > " '
+ *
+ * - Character references
+ *
+ * - Sections marked as CDATA
