Do you mean the built-in "language-xml" package or something else? FWIW, I have it enabled.

Yes, I'm using the built-in language-xml version 0.34.2.
I sure hope it doesn't try to highlight the entire thing, and instead just what is visible on-screen.
With most languages and things like XML it will need to have parsed from the start to the visible area to understand the context (e.g. what if there is comment that started 1000 lines earlier but hasn't yet been closed).
