Subject: [Megaco] Various error reply patterns

Dear all,

I have one question about the error reply pattern.
For example, if MGC sends the following partially wrong 
request message:

!/3 [x.x.x.x]:2944
T = 1 {
   C = $ {
     A = john/$ { (correct description) },
     A = doe/$ { (wrong description) }
}}

Then, the second action will be not completed.
At this point, what error reply is expected?

Answer.1)
!/3 [x.x.x.y]:2944
P = 1 {
   C = 1 {
     A = john/1 { (normal reply) }},
   C = $ {
       ER = (error code) { (error text) }
     }}

Answer.2)
!/3 [x.x.x.y]:2944
P = 1 {
   C = 1 {
     A = john/1 { (normal reply) }},
     ER = (error code) { (error text) }
     }}

In case of 1, I think it is correct because the related 
action was not completed. (though the contextID has been 
resolved on the former action...) In ABNF, this is not 
improbable.
In case of 2, it is not out of way.
Are there various patterns in this case?

Could you give me some advices?

Thank you for your help in advance.
Kind regards
