It's all xpath semantics as far as I know.

I was told that SAML needs a thing the built in xml library doesn't
support. I doubt that any other projects really need it. However, there
would be a ton of unwind in nova to get rid of it given how extensively
it's used in libvirt driver.

I don't know about other projects. It also only benefits us if we can
remove it from g-r entirely.
