Are there any license limitations to redistribute DOM IDL files?

Hi,

I am working on an (opensource) project; part of it is based on DOM
IDL files converted into declarations in other language (Haskell). It
would be convenient to include the DOM IDL files into the project
distribution rather than have every user of the project to download
from the w3 website and unzip them before conversion.

Are there any license limitations on such redistribution, or is it
advised that these files are to be downloaded from w3.org every time?

Thank you
