DTP DTD?

Hello,

Before I bravely reinvent the wheel, is anyone aware 
of DTDs describing the underlying layout models of 
Adobe InDesign or Quark XPress, as exposed by their 
scripting APIs (at least on the Mac)? The aim is
to apply XSL-transformation to a XML content file
towards an intermediate tree representation, then
create DTP files from this tree using the scriptability 
of the DTP program. (I'm not talking here about FO.)

Thanks in advance for any answer, suggestion or link!
