1.0 Introduction

1.1 Project/Component Working Name:

    libexpat[1] upgrade and move to /usr
    
1.2 Purpose

    This project will deliver an updated version of libexpat into
    Solaris and moves it from /usr/sfw/lib to /usr/lib.

    The current version of libexpat in /usr/sfw is 1.95.7.  

    Some applications/utilities in Solaris use their private or static
    version of libexpat: apache2 uses private 1.95.2 and Python uses
    1.95.8, statically linked.  Both cases have the danger of conflicting
    with code that uses the shared libexpat.  In the case of Apache,
    this has been known since 2004, see CR 4840891, but it has not
    caused any known problems.  In the case of Python, this is causing
    crashes in the GNOME desktop, see CR 6531456.  Python cannot be
    made to use the shared libexpat without updating it, because
    it depends on APIs introduced in 1.95.8.

    The requested release binding is Patch.
