Thanks Michael,

sorry I want to do something different. I want to have "MiddleThree" and
"MiddleFour" and much more inside "OuterOne" and "OuterTwo". Definitely
"OuterOne" and "OuterTwo" will have different tags inside, but I took =
all
other tags out trying to mention my problem. If I am getting up tp
"MiddleThousand" I do have to write thousand refs in both. Because I =
have
many "Outer" too, my schema explodes. With only one reference it would =
not
explode. 
Is that clearer?
Udo

Betreff: RE: Referencing similar lists through a complexType


There's something wrong with a design that uses element names "OuterOne" =
and
"OuterTwo" and envisages extending this to "OuterThree" and "OuterFour". =
It
suggests that you're packing data into the element names, whereas they
should be used only to indicate the structure.

Replace <OuterOne ...> with <Outer level="1" ...> and your processing =
will
become much simpler.
