The Liber Pontificalis is not Sacred Scripture, and not I but the source quoted said that the decree attributed to Saint Peter's first successor is probably apocryphal.  Is anything else attributed to Pope Linus?  Or was this the most important thing he did as Pope?  By all means mention that the Liber Pontificalis is said to contain that information.  It was by oversight that I omitted the mention of the Liber Pontificalis, though the fact that I have no way of checking that the Liber Pontificalis contains that statement probably hd some subconscious part in my forgetfulness.
The question of women wearing pants came to mind because of the probability that the decree attributed to Pope Linus is aprocryphal. The letter of Pope Nicholas I is certainly genuine.  I should indeed have stated explicitly that traditionalist women are, I think, less likely to go to Mass wearing pants than without a veil, and so the question of pants deserves to be listed among traditionalist practices as much as the question of the veil.  If the pants question disappears from the footnote, I will certainly consider putting it in the body of the article.  By all means add the point that I regrettably forgot to mention: that traditionalists do not like women in pants at Mass.
