[Simple-support] positions of elements

[gato c. <da...@gm...>]

Hi
I have a class like next one:
class A{
    @Element
    B b;

    @Element
    C c;
}

result at parsing:

<a >
   <b>
   <c>
</a>

How can I change the positions of elements?, in order to get:

<a >
   <c>
   <b>
</a>

Thanks a lot.
