Hi,

>> As has been indicated, bundle-only can only be used when one knows that the receiver, and possible intermediaries etc, support it.

Discuss what???

In general, the current version of BUNDLE is based on the usage of 2 Offer/Answers - which is something you have agreed to.

If you only refer to bundle-only lines, that is a discussion that has just started...

Christer
