&installation.enabled.disable; `--disable-xml`

These functions are enabled by default, using the bundled expat library. You can disable XML support with `--disable-xml`. If you compile PHP as a module for Apache 1.3.9 or later, PHP will automatically use the bundled expat library from Apache. If you don't want to use the bundled expat library, configure PHP with `--with-expat-dir=DIR`, where DIR should point to the base installation directory of expat.
