European Council (Art. 50) guidelines for Brexit negotiations

"It will be constructive and strive to find an agreement."

Seen very little of that so far from the EU's negotiators.

"Negotiations under Article 50 TEU will be conducted in transparency and as a single package. In accordance with the principle that nothing is agreed until everything is agreed, individual items cannot be settled separately."

The above is not the manner that the EU negotiators are insisting upon - Is it?
