Its license seems compatible:

However it, too, is valid XHTML 1.0 Transitional. Where's some invalid HTML when you need it?! :)
Here are two suggestions for performance-testing invalid HTML before turning on the new parser:
1. Write a fuzzer-like script to invalidate these valid HTML files by leaving off some closing tags, adding invalid parent nodes, removing the <head> tag and putting its contents directly in the <body>, and things like that.
2. When you're ready, ask someone at Apple to try the PLT with the new parser. It's not redistributable, but there's plenty of invalid HTML in it.
