[xml] Problem whit --with-schemas in ./configure

[soriano_s tsm es]

      Hi, when I see the system configure whith libxml2 2.5.1 in Solaris
5.8

            ./configure --help

      shows me:

            --with-schemas              Add experimental Schemas support
(off)


      At that point I cofigure:

            ./configure --with-schemas


      and then  the "./configure --help" show me the same information.

      How can I activate the schemas ???????

      Please, help me.
