Cross referencing in Ddoc

[Ola Fosheim Grøstad" <ola.fosheim.grostad+dlang at gmail.com>]

XSLT is pretty useful for format conversion. It is also built 
into most browsers, so you can just emit XML attach a XSLT 
stylesheet and send it to a browser for transformation and 
rendering.

Would be an advantage for anyone writing a book or article on D 
(transform XML over to docbook, and from there to any format).
