building book does not work about watchmaker

Thanks for letting me know. The book target isn't really intended for public consumption, I was just be being lazy in not creating a separate repo. There is nothing of value in it that is not already in the HTML version of the manual on the website. That said, it ought to work, and it did work. Bizarrely, it now fails for every version of the repository, right back to the intial DocBook source from 3 years ago.

Since the DocBook stylesheets and almost the entire toolchain are stored in the repository and haven't changed recently, I'm not sure what broke it. The error is coming from FOP but I think maybe it was treating these errors as warnings before.

Eventually figured out that this was due to a different default XML parser being used instead of the Xerces parser that was used previously. Fixed to ensure that it always uses Xerces.
