# Purposefully dropped the xml USE flag and libxml2 support. Having this is
# silly since expat is the preferred way to go per upstream and libxml2 support
# simply exists as a fallback when expat isn't around. expat support is the main
# way to go and every other distro uses it. By using the xml USE flag to enable
# libxml2 support, this confuses users and results in most people getting the
# non-standard behavior of libxml2 usage since most profiles have USE=xml
