[SR-Users] xavp questions (variables in root/branch)

[Vasiliy Ganchev]

Hi, Daniel!

I expected to use it per transaction. We are also actively using htables for
different cases, and I am aware of them.

My question about xavps - was "in general" - is it a limitation of the
initial design, and is it planned to be changed.

For now, instead of using xavp with variables, I am using AVPs with complex
names (name consists of 2 vars)  - and it does what I needed.

Thanks for your answers!

Best regards, Vasiliy
