no, you can still write them. but if you do so,
you have to have a little understanding
of what you are doing. What you cannot
do in Relax is take

   model.foo.seq = a, b, c

and extend it to add "d" on the end

same thing. If you say

   x.model.foo.seq = a |

you get a weird result.  this simply needs documenting.

I have never understood how to write extensions
natively in XSD anyway, so no comment!

I am glad to see your jet lag is being so productive...
