Hi John, Yes, this does make it a little bit more clear, but questions remain. I understand that if you want to modify one of the elements you have to send it in a Modify request as a standalone element. So if I want to modify two elements I have to send them in two separate elements like below? <p2p:capacity>500</p2p:capacity> <p2p:parameter type="protection">UNPROTECTED</p2p:parameter> I'm I correct that this implies that it is not allowed to send a complete p2p element with all the elements in it and only change the ones you want modified? Furthermore, the first paragraph says that only the elements to be modified are included in the request, but the second paragraphs says that if a modification request contains modifiable elements that are the same as the currently reserved values, the modification request should proceed through the reserve state machine lifecycle as if changed values were successfully applied, effectively only increment the criteria version. So is it allowed to send elements that did not change or not? Cheers, HansT. On 23/11/2016 16:44, John MacAuley wrote:
I will read the section again since it must not be clear. Here is what a modify message looks like for capacity:

This is include only the capacity element that is defined in the p2p schema as a standalone element for the purposed of modification. This is not including the full <p2ps> element and using optionality. It is including the <capacity> element. If you look at the p2p service schema this is parameter defined as modifiable in the p2p service (startTime and endTime are in the CS schema itself).
You may ask why it was done this way… It allowed us to have the original reservation request have mandatory elements for the service, but the modify to only contain those elements being changed.
Does this make it any clearer?

Dear NSI WG members,
The CS 2.1 document states in section 15.7 that only the elements to be modified are included in a modify request. However, in the schema the p2p parameters directionality, capacity, sourceSTP and destSTP are not optional. As a result the example modify requests in figure 154 and 155 will not pass schema validation.
If the four parameters are made optional in the schema it will also be possible to leave them out in the initial reserve request, which will cause problems because all four of them belong to the minimum set of parameters in this stage. Or the schema is left as is making it mandatory to always send the minimum set of parameters in every modify request, in this case section 15.7 should be updated to reflect this.
Please advise how to proceed.
