There isn't any way to express this in Ecore.

If you try importing such a model and then exporting it to a schema
(which is a handy way to see the @model annotations that correspond to
any particular type of schema construct) you'll see it ends up coming
out as <xsd:sequence/>

You'll find the issue of choice comes up fairly frequently and the above
bugzilla is our oldest bugzilla. But it's also a tough problem to solve
in general, given that choice is not well supported in EMOF, UML, and
Java...
So it seems best to consider these just to be separate features that you
constrain to be mutually exclusive...

I'm trying to model a xsd file with Java annotations. I don't know how
to express this piece of code:

<xsd:complexType>
