maybe it was true in some old version, but looking at llvm 12.0.1, clang[xml] only enables c-index-test, which seems not used by lldb. libxml2 seems more important for lldb, used for gdb remote and plist parsing. neither of these seem critical though, and doesn't need to pull in clang[xml], only libxml2 directly.
You are probably correct. I don't really recall why we did that but I suppose LLDB might have used clang's variables for determining whether libxml2 was available. Nowadays it checks for it itself.
