I hate to play the "no it didn't" game, but, no, it didn't. There were something like 10 errors, which I verified by actually looking at the file. Things like missing close tags (not optional ones, but on stuff like <sect2>), a "<para>" where there was supposed to be a "</para>"... I got largely the same errors with OpenJade's nsglms and xmllint (after changing the DTD to Docbook XML 4.1.2). Regardless, if you know you *should* validate the document, that is the most important thing, since using structured markup would be a waste otherwise.

Update: the file was changed after I posted my responses so that the HEAD revision no longer has the errors I mentioned (ok, I guess it was 5 errors, not 10, but same difference). I really think it is obnoxious of hacker to do this and claim I'm the one who is wrong... Did he not just update the CVS after I pointed out the errors, as verified by the RCS tag?
