These files are needed at runtime to construct the Schema object used for validation. So IMO they need to be in any binary distribution so validation works without an internet connection. So I think including them in svn and source makes what's going on clear and is much simpler. > > If the Jaxb code is in OpenEJB, then OpenEJB would seem like the natural > location.
