Log Message:
Updated to version 1.63.

Pkgsrc changes:
  - Added support for installation to DESTDIR.
  - Registration of the parser happens through the pkginstall framework
    (INSTALL/DEINSTALL) now, thus making the MESSAGE file unnecessary.
    Setting SKIP_SAX_INSTALL in the environment and replacing
    PERL5_INSTALLVENDORLIB in the install scripts is necessary for this to
    work.

Changes since version 1.62:
==============================
1.63
   - added no_network parser flag
   - added support for exclusive canonicalization \ 
(http://www.w3.org/TR/xml-exc-c14n/)
   - make XInclude reflect parser flags
   - documentation fixes
   - better namespace reconciliation implemented by Tim Brody
   - $doc->toString always returns octets
   - $doc->actualEncoding returns UTF8 if no document encoding is declared
     (unlike $doc->getEncoding, which returns undef)
