InDesign export Text Layout Framework Markup

hi there

as described in title, i'm having troubles exporting an InDesign comp in a decent way

my quesitons are:

1 - It exists a DTD for Text Layout Framework Markup Language ?

2 - Is there an export module that make me able to do it automatically? because tagging all the elements is a pain, and there is just a little documentation about the markup language

If not, are there any plans to do it?

I personally think that an export module will be very helpful and will score another goal on products' integration

Thanx for your time
