This obviously isn't anything concrete - consider it your 'starters for
What I envisioned happening was that the LFS Book would contain a mix of
DocBook and nALFS tags. The LFS stylesheets would add a customisation
layer that would render the information provided in the nALFS tags into
appropriate human-readable output. The nALFS tool would then simply
parse the book, picking out all the nALFS tags, throwing away the
DocBook ones, and doing what it needs to do.
How Relax NG fits in to it is that in order to mix and match tags from
different XML structures, one needs to use an XML Schema definition
rather than the SGML-based DTDs we currently use. There are a number of
such Schema varieties out there, the W3Cs XML Schema Definition (XSD)
being one of them. So why choose RelaxNG? The DocBook committee has
already outlined its plans for providing the DocBook-5.0 schema in Relax
Hope this helps at least a little, let me know where it needs
'concreting' and where such text needs to be made available.
