Re: trang and xsd-friendly schemas

Sebastian

  James' idea is elegant, but I don't think it solves the problem of 
  interleave, because
  the outer schema will be more restrictive. ie if it says
    a = x, y, z
   whereas the inner one says 
    a = x  & y & z

Yes but you could make your outer one something less restrictive and
xsd/dtd-friendly such as (x|y|z)* or even something equivalent and
xsd/dtd-friendly such as (x,((y,z?)|(z,y?))|y,((x,z?)|(z,x?))... etc
