If you build libxml2 from the master branch, have a look at this commit and make sure that RELAX NG is enabled.

i did by building libxml2 with -DLIBXML2_WITH_RELAXNG=ON. it still failed.

Should be fixed here: https://gitlab.gnome.org/GNOME/libxml2/-/commit/66fdf94c5518547c12311db1e4dc0485acf2a2f8

There's no need to add -DLIBXML2_WITH_RELAXNG=ON which is enabled by default.
