This is needed for XSLT to keep the stylesheet dictionnary read-only while being able to reuse the strings for the transformation dictionnary. * xinclude.c: fixed a dictionnar reference counting problem occuring when document parsing failed. * testSAX.c: adding option --repeat for timing 100times the parsing * doc/* : rebuilt all the docs Daniel
