RE: C type array and struct

Thnaks Jeff,

I think you are write that the only way of specifying unnamed sub elements
is the <any> element in the schema. But I think this is a series shortcoming
in the present schema.

Does anyone out there know if this is an issue for the next schema spec. 

regards,
Ayalew
