Best tool(s) for working with DocBook XML documents?

Using xml: Best tool(s) for working with DocBook XML documents? on newest questions tagged xml – Stack Overflow

I experimented with DocBook XML a while back, and also used it professionally for documenting a few software projects, but since the tool support at the time was not very good, I soon abandoned it in favor of hand-written LaTeX, and later LyX.

Now I’m considering taking another look at DocBook, and I was wondering, what are the best tools for working with DocBook XML documents today?
