Angle brackets get lost in non commutative powers in wxmaxima.

Hi,

Non-commutative powers should be in angle brackets as in:

(%i1) a . a . a;
                                      <3>
(%o1)                                a

However, in wxmaxima, if xml format is chosen for the output they do not
appear. Is there any way to get them back again?

Cheers,

Bernard.
