MarsSeed [1] filed a deletion request for qt5-xmlpatterns-git [2]: I suggest this legacy VCS package can be deleted. This currently points to official qt 5.15 branch, but that is not the most up-to-date public version. Arch carries extra/qt5-xmlpatterns. That package has KDE's patches on top of the official qt 5.15 branch, with Qt Company's blessing. The patches are actually selectively cherry-picked from official closed-source Qt 5.15 git by KDE. Arch/extra/qt5-xmlpatterns is pretty much the git branch head (latest public version) of v5.15.x Qt libraries. Therefore there is no need for this VCS package, Arch official repo builds very frequently from the aforementioned branch.
