David,

But to create a Text inside a Group becomes a problem since Group has setText().

To handle that rare case, XSWT has an <x:children> meta-node.  So you can write:

<group>
  <layout x:class="fillLayout">

This is like xsi:type I assume.  Think of how you'd do this in JSON.  It's important to have this information early...

Yes, I think.  XSWT does type inferencing to know the type of object to construct.  But when you have:

#setLayout(Layout)

the programmer must explicitly supply which concrete subclass of Layout to construct, which is the purpose of the x:class meta-attribute.
