Sorry, I'm not entirely sure I understand your question. When you say "message wall profile", are you talking about the Wall Greeting?
If you are, I think something like this should work:
<tabber>
|-|First Tab Title=
First tab sample text.
|-|Second Tab Title=
Second tab content goes here.
|-|Third Tab Title=
Third tab content goes here.
</tabber>
