SGA 7, tome 1, exp. IX, contains in its introduction and in section 13.4 remarks about ideas and conjectures of Deligne on a “théorie de Néron pour motifs de poids quelconque”. Would someone please give an epitome of that theory or references? (This is Thomas Riepe's request http://sbseminar.wordpress.com/requests/#comment-3717 at the secret blogging seminar, mildly edited.)

Also, would a kind administrator please tag this "neron-models", then scrub this line off? Thanks so much!
