Re: DTP Formats

[John MacFarlane <fiddlosopher-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

One approach could be to keep a global stack of attributes.

function Strong(el)
  -- add "Strong" to the attribute stack
  -- process the children of el
  -- remove "Strong" from the top of the attribute stack
end

function Str(el)
  -- get all the attributes from the current attribute stack
  -- output an ITEXT node with these attributes
end

In the first test I tried to solve it by pure regex, lol, it worked except the inheritance of inline atrributes. In the second try it seems it could work, but I have to continue working and refactor the code for the classic writer --- to late I come to realize that the new writer works when you don't need to rewrite everything, which it is not this case.
