This import has 3 difference with upstream:
They are fairly small differences, and they should alight with further sync.

Oh you wouldn't have to go very far to find something wrong with that parser. First thing, it's a fork of the jscript parser, which is wrong on its own. Secondly, support for an XML dialect was thrown in there, well, let's say, quickly. And if you're still standing and keep digging, you'll see that what's left is not so bad (well, not worse than jscript), but doesn't extract much info (no signature, no inheritance, no type, etc.).
This said, it still should work OK, and give somewhat better results than the previous one.
