* Parsers:
  - Validation now supported: Use Parser::set_validate() to turn on validation. 
    Parsers will then throw validation_error exceptions if validation fails.
    (Murray Cumming)
  - SaxParser: Added parse_chunk() for gradual parsing of XML fragments.
    (Ole Laursen)
* Node:
  - Moved add_child_content(), get_child_content(), set_child_content(), 
    and has_content() to Element class.
  - Fixed set_child_content() to add content instead of creating a node.

* The imlementation now uses libxml's API more instead of reimplementing data structures.
  (Stefan Seefeld, Murray Cumming)

  (Stefan Seefeld)
* Node: Added get_path() and find() for xpath lookup. (Stefan Seefeld)

    Added CDATA section handler.
    fixed a potential buffer overflow problem

* big API change for nodes handling : the different types of node now herit
from a base Node class. This, among other advantages, avoids previous ambiguity
on content() acessors meaning.
* little bugfixes and improvements in SaxParser.
