 * 		Undefined if also specify subfields
 * k - invoke 'kustom' format_func for output, can use subfields for input
 * 		Leading and trailing whitespace trimmed.
 * 		Enforces that if subfields are specified, no content is	allowed
 *		It is expected that fields without subfields will have explicit
 *		end_func to process them.
 * t - invoke 'kustom' format_func for output, can use subfields for input
 * 		Leading and trailing whitespace not trimmed.
 * 		Enforces that if subfields are specified, no content is	allowed
 *		It is expected that fields without subfields will have explicit
 *		end_func to process them.
 * w - wildcarded tag format.
 * 		Leading and trailing whitespace not trimmed.
 * 		Enforces that if subfields are encountered, no content is allowed
 * 		An end_func should be supplied to handle input, especially when
 * 		no subfields.
 *		Typically used in conjunction with tag name of '*' to permit IXml
 *		parser to implement a stack but manually do tag processing in Start
 *		and End functions.
 * y - trimmed wildcarded tag format.
 * 		Leading and trailing whitespace trimmed.
 * 		Enforces that if subfields are encountered, no content is allowed
 * 		An end_func should be supplied to handle input, especially when
 * 		no subfields.
 *		Typically used in conjunction with tag name of '*' to permit IXml
 *		parser to implement a stack but manually do tag processing in Start
 *		and End functions.
 *
 * The IXmlParserState and IXmlOutputState structures should be treated
 * as opaque structures.  format_func, end_func and start_func should not
 * use fields in these structures.  The necessary information from the state
 * is supplied as explicit arguments.
 *
 * Output:
 * each field is processed in order.
 * If format_func is specified it will be called (regardless of format)
 * with data pointer pointing to present object + offset.
 * If no format_func is specified, the offset and size will be used along
 * with the format to automatically fetch the field and generate output
 * 'k', 't', 'w' and 'y' formats must supply a format_func.
 *
 * Input Parsing:
 * On input parsing, capital letters for format indicate manditory fields
 * Present implementation is limited to no more than 64 manditory fields
 * per object
 *
 * On input parsing, if a start_func is supplied an end_func must also
 * be supplied.  If a end_func is supplied, format is not used to parse
 * data but affects whitespace and subfield processing.
 * An end_func should be supplied for 'k'/'t'/'w'/'y' formats, otherwise
 * the input field will be ignored (recommend use of IXmlParserEndNoop
 * rather than NULL for future compatibility).
 *
 * On output processing, capital letters for format indicate manditory fields
 * which are always output regardless of value.  lower case leters for format
 * are optional fields which will only be output if non-zero/non-NULL.
 * For 'k', 't', 'w' and 'y' fields, its up to the supplied format_func to
 * decide.
 * There are "Optional" variations of most generic format functions which may
 * be used by format_func if desired.
 *
 * For an output only field:
 * 	type/format_func define output
 * 	start_func=NULL, end_func=IXmlParserEndNoop
 * For an input only field:
 * 	type/start_func/end_func define input
 * 	format_func=IXmlOutputNoop
 * For an input/output field:
 * 	type/start_func/end_func define input
 * 	type/format_func define output
 *
 * Error handling:
 * Failures in XML syntax or calls to IXmlParserPrintError will stop
 * the parser with an error.  For such parsing failures, the parser
 * will unwind and invoke the end_func's for all objects whose start_func
 * had been called.  Such calls will have valid=FALSE.  In this case
 * the end_func should undo any operations which the start_func did
 * (free object, remove object from lists in parent to which start func added it
 * etc).
 *
 * If a start_func or end_func encounters a fatal error, it should call
 * IXmlParserPrintError with an appropriate message.  This will output
 * a message including input file line, present tag and the message
 * provided by the caller.  It will also start the parser error and unwind
 * sequence.
 *
 * Once a parser error is detected, no further start_func's will be called.
 *
 * Object handling:
 * The parser assists in tracking object heirachies and provides objects
 * to the start_func and end_func.  The start_func is expected to return an
 * object pointer.  This pointer is typically an object/structure allocated
 * by the start function to hold the subsequent tags.  The pointer returned by
 * the start_func will be provided to the end_func as the "object" argument.
 * Also if there are nested tags (eg. subfields), the object returned by
 * the start_func will also be provided to the nested tags' start_func and
 * end_func as the "parent".
 *
 * Typical operation would be for the start_func to allocate and initialize
 * the empty object.  For simple structures which simply need to be
 * allocated and zeroed, the IXmlParserStartStruct function is provided.
 * Then the end_func would verify the consistency of the fields and link the
 * object into its parent (add to a list or pointer).  If the end_func discovers
 * an error it should call IXmlParserPrintError (or Warning if its non-fatal)
 * and free the object.
 *
 * For simple fields (bitfields, needing special handling, etc).  The
 * start_func can be NULL and the end_func will be given the object and
 * parent applicable to the preceeding tag.
 *
 * The code in ixml_ib.c is a good example of use of the parser.
 *
 * xml_sample provides a simple example of a parser which uses the
 * wildcards to parse and dump any XML file given.
 *
 * opaxmlindent expands on xml_sample by dumping the XML with nice indentation
