Hi Bernhard
Yes, every feature should have a unique id. The data provider class
which creates the features decides which id to give.
QGIS also relies on feature ids, e.g. for identifying features when
editing.

Marco

Hi devs,
I wonder if I can assume that any _polygon_ feature has an id,
regardless of the format it comes from (given it is either file or
db-based). In a plugin I am currently working on, I rely on every
feature having an id.
