This feature requires a two--step process, in which the nuclearly processed matter from a first generation (FG) of stars gives birth to a second generation (SG) bearing the fingerprint of a fully CNO-cycled matter. Since the present population of most globular clusters is made up largely of SG stars, a substantial fraction of the FG (>~90%) must be lost. Nevertheless, two types of clusters dominated by a simple stellar population (FG clusters) should exist: either clusters initially too small to be able to retain a","authors_text":"F. D'Antona, V.
