To: xmlschema-dev@w...

 HI Noah,

Thanks for the response. I completely agree with you.
But is there a possiblity of revisiting the "xsd:all" semantics in the near
future.
i.e. either nuking it, and thus enforcing order always.
     OR
     removing just the restriction on the member cardinalities in the "all"
compositor.

rgds,
Menon
