[ome-devel] XSV crash on wildcard item

[Ilya Goldberg]

Isaak,
Thank you very much for this.  Allowing more tools to work with this  
stuff is most welcome, and MS XML compatibility is a big, big plus.
I committed these changes and they should go live sometime tomorrow.   
Arity of '*' (zero or more) is exactly the right setting for this  
element anyway.
Hooray!
-Ilya
