That's even worse than I thought. Especially this disclaimer consideration:

“This is open-source software written by hobbyists, maintained by a
single volunteer, badly tested, written in a memory-unsafe language and
full of security bugs. It is foolish to use this software to process
untrusted data.”

No wonder other major databases opt for writing their own XML processing
engines. Sadly, despite these issues, there doesn't seem to be a decent
alternative to libxml2 :(
