[Om] OpenMath in Wikipedia: was[Fwd: Problematic cases for inria parser]

[Professor James Davenport]

One of my students writes as foolows, and it is item 3 that worries me.
Compared with OMSTD 2.0, the Wikipedia is wrong.
Shall I just correct it?

 These are the things that the INRIA parser doesn't recognise. I think the
parser is based on version 1.0, as these things do not appear in Standard
1.0.

   This appears only in the example in Wikipedia
http://en.wikipedia.org/wiki/OpenMath,  I didn't find it in any other
examples and in the standard, so it might be illegal.
