Compound requests with inner Pending requests

Hi all,

While trying to design some scenarios for the XKISS interop tests I came
across an issue about compound requests:

In par.[83] of the specification it is stated that "a client MAY issue a
compound request containing multiple inner pending requests...".

However, the schema doesn't allow PendingRequest elements to be included
in a CompoundRequest element. If we follow the schema PendingRequests
have always to be done separately and never put together in a compound
message.

Should a change in the schema be done to include PendingRequest elements
in CompoundRequest elements or should the specification be corrected (or
should I notice something I've missed;)?
