Hello Martin,

thank you for your response, I know how to implement completion. What 
I'm inquiring about is how to implement the collection of completion 
candidates from multiple buffers. I can implement this in my mode, 
however I'm wondering if Emacs already has a facility for this kind of 
things.

Cheers,
Dan
