2	* parser.c : an XML 1.0 parser, namespaces and validity support are mostly
3	* implemented on top of the SAX interfaces
4	*
5	* References:
6	* The XML specification:
7	* http://www.w3.org/TR/REC-xml
8	* Original 1.0 version:
9	* http://www.w3.org/TR/1998/REC-xml-19980210
10	* XML second edition working draft
11	* http://www.w3.org/TR/2000/WD-xml-2e-20000814
12	*
13	* Okay this is a big file, the parser core is around 7000 lines, then it
14	* is followed by the progressive parser top routines, then the various
15	* high level APIs to call the parser and a few miscellaneous functions.
16	* A number of helper functions and deprecated ones have been moved to
17	* parserInternals.c to reduce this file size.
18	* As much as possible the functions are associated with their relative
19	* production in the XML specification. A few productions defining the
20	* different ranges of character are actually implanted either in
21	* parserInternals.h or parserInternals.c
22	* The DOM tree build is realized from the default SAX callbacks in
23	* the module SAX.c.
24	* The routines doing the validation checks are in valid.c and called either
25	* from the SAX callbacks or as standalone functions using a preparsed
26	* document.
27	*
28	* See Copyright for the status of this software.

3396	* - a character reference is processed by appending the referenced
3397	* character to the attribute value
3398	* - an entity reference is processed by recursively processing the
3399	* replacement text of the entity
3400	* - a whitespace character (#x20, #xD, #xA, #x9) is processed by
3401	* appending #x20 to the normalized value, except that only a single
3402	* #x20 is appended for a "#xD#xA" sequence that is part of an external
3403	* parsed entity or the literal entity value of an internal parsed entity
3404	* - other characters are processed by appending them to the normalized value
3405	* If the declared value is not CDATA, then the XML processor must further
3406	* process the normalized attribute value by discarding any leading and
3407	* trailing space (#x20) characters, and by replacing sequences of space
3408	* (#x20) characters by a single space (#x20) character.
3409	* All attributes for which no declaration has been read should be treated
3410	* by a non-validating parser as if declared CDATA.

3412	* Returns the AttValue parsed or NULL. The value has to be freed by the caller.

7834	* - a character reference is processed by appending the referenced
7835	* character to the attribute value
7836	* - an entity reference is processed by recursively processing the
7837	* replacement text of the entity
7838	* - a whitespace character (#x20, #xD, #xA, #x9) is processed by
7839	* appending #x20 to the normalized value, except that only a single
7840	* #x20 is appended for a "#xD#xA" sequence that is part of an external
7841	* parsed entity or the literal entity value of an internal parsed entity
7842	* - other characters are processed by appending them to the normalized value
7843	* If the declared value is not CDATA, then the XML processor must further
7844	* process the normalized attribute value by discarding any leading and
7845	* trailing space (#x20) characters, and by replacing sequences of space
7846	* (#x20) characters by a single space (#x20) character.
7847	* All attributes for which no declaration has been read should be treated
7848	* by a non-validating parser as if declared CDATA.
7849	*
7850	* Returns the AttValue parsed or NULL. The value has to be freed by the
