libxml2

• --with-history depends on libedit and netbsd-curses
• Do not depend on icu
• Some distributions enable legacy for ABI compatibility
• In legacy mode support for http, lzma and zlib is enabled by default
• The legacy configuration option won’t enable support for HTTP and LZMA anymore. These features will be removed in the next release.
• SAX1 is deprecated
• Test suite is optional and requires additional download xmlts on LFS?
• Support for FTP and xpointer() XPath extensions has been deprecated
• Should we leave xinclude enabled? or is it deprecated as well?
• Check OpenBSD for bsdtar patches to xstc
• Explicitly specifying --with-legacy or removing without-sax1 prevents libxkbcommon from breaking as of 1.8.0 as test/registry.c fails with xmlParseMemory errors when xkbregistry is enabled; libxkbcommon builds fine if xkbregistry is disabled
