- * parser.c : an XML 1.0 parser, namespaces and validity support are mostly
- * implemented on top of the SAX interfaces
- *
- * References:
- * The XML specification:
- * http://www.w3.org/TR/REC-xml
- * Original 1.0 version:
- * http://www.w3.org/TR/1998/REC-xml-19980210
- * XML second edition working draft
- * http://www.w3.org/TR/2000/WD-xml-2e-20000814
- *
- * Okay this is a big file, the parser core is around 7000 lines, then it
- * is followed by the progressive parser top routines, then the various
- * high level APIs to call the parser and a few miscellaneous functions.
- * A number of helper functions and deprecated ones have been moved to
- * parserInternals.c to reduce this file size.
- * As much as possible the functions are associated with their relative
- * production in the XML specification. A few productions defining the
- * different ranges of character are actually implanted either in
- * parserInternals.h or parserInternals.c
- * The DOM tree build is realized from the default SAX callbacks in
- * the module SAX.c.
- * The routines doing the validation checks are in valid.c and called either
- * from the SAX callbacks or as standalone functions using a preparsed
- * document.
- *
- * See Copyright for the status of this software.

- * - other characters are processed by appending them to the normalized value
- * If the declared value is not CDATA, then the XML processor must further
- * process the normalized attribute value by discarding any leading and

- * - an entity reference is processed by recursively processing the

- * #x20 is appended for a "#xD#xA" sequence that is part of an external
- * parsed entity or the literal entity value of an internal parsed entity
- * - other characters are processed by appending them to the normalized value
- * If the declared value is not CDATA, then the XML processor must further
- * process the normalized attribute value by discarding any leading and
- * trailing space (#x20) characters, and by replacing sequences of space
- * (#x20) characters by a single space (#x20) character.
- * All attributes for which no declaration has been read should be treated
- * by a non-validating parser as if declared CDATA.
