AS4 Section 5.1.8 Generating Receipts Profiling Rule (a) confusion

[Theo Kramer <theo@flame.co.za>]

Hi

Section 5.1.8 Generating Receipts Profiling Rule (a) of the AS4 spec reads as follows

When a Receipt is to be used solely for reception awareness, the sender of the Receipt MUST contain a copy of the eb:UserMessage structure of the received AS4 message.

This is open to misinterpretation as it could mean that either the receipt must contain a copy of the eb:UserMessage structure or the Sender must keep a copy of that. My thinking is that it should read as one the following

1  When a Receipt is to be used solely for reception awareness, the sender of the Receipt MUST retain a copy of the eb:UserMessage structure of the received AS4 message.

or

2  When a Receipt is to be used solely for reception awareness, the sender must include a copy of the eb:UserMessage structure of the received AS4 message in the receipt.

Comments or other suggestions ?
