MarsSeed [1] filed a deletion request for lsp4xml-git [2]: Project moved to Eclipse and renamed to lemminx. There's a stable package for that but not a VCS one. But this one is best be deleted: not updated since 2018; no votes or comments. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/lsp4xml-git/
