Hello everybody.

It is posible do complex type content dependent of a attribute value
without xsi:type?

Next, is a example. TYPE content depend of class attribute values.

The next schema have two error.

First, VINIT element are diferent type on schema and I get one error
form  Schema validator.

After, content TYPE element are "unbounded" to class attribute, so, is
valid write a "bool" class atribute with a enum content.

Thanks in avance.
