Thanks Roberto! I was able to make the acs core docs by upgrading the libxml, libxml2 and the libxslt rpms to the latest versions that I could find (I use
http://rpmfind.net). What we have now on our RedHat 7.2 server is:
# rpm -qa|grep libxml2
libxml2-devel-2.4.24-1
libxml2-2.4.24-1
# rpm -qa|grep libxml
libxml-1.8.17-6
libxml2-devel-2.4.24-1
perl-libxml-perl-0.07-5
libxml2-2.4.24-1
libxml-devel-1.8.17-6
libxml10-1.0.0-8
perl-libxml-enno-1.02-5
# rpm -qa|grep libxslt
libxslt-progs-1.0.20-2
libxslt-devel-1.0.20-1
libxslt-1.0.20-2
# xsltproc -V
Using libxml 20424, libxslt 10020 and libexslt 711
xsltproc was compiled against libxml 20424, libxslt 10020 and libexslt 711
libxslt 10020 was compiled against libxml 20424
libexslt 711 was compiled against libxml 20424
