+/*
+ * 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

+ * character to the attribute value
+ * - 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.
