Discussions between team members using package version control

[philipp.k]

Hi together,
I am wondering how the discussions are working in EA and have two questions:
1)
We are using version controlled packages and I am able to add a discussion to an element in a locked and checked-in package of a colleague...
Where are those discussions stored? How my colleague is receiving this discussion on his element? Are those stored in the *.eapx file?

2)
When communicating with the (company external) system stakeholders, is there a way, that they can add discussions to elements, which I can import back in the model without importing the complete package?

thx,
philipp
