Relax NG is only tool which can be used to formally and precisely
describe syntax of DocBookNG.
Of course you can describe document type and all its content models in
prose, in human readable text. But this will be very verbose and very
hard to use description.
As Relax NG doesn't have features like attribute defaulting its usage
has no sideeffects and you don't need process RelaxNG grammar in order
to process DocBook (however this is not true for DTD). But there
definitively should be formal description of DocBookNG grammar, this
formal description should be normative and Relax NG is the most suitable
tool for this task at these days.

P.S. I notices that I'm using DocBookNG instead Norm's DocBook V.next
label. But I mean the same.
