The Gemoro in [Rosh Hashono 17b](http://www.mechon-mamre.org/b/l/l24.htm) says that HKB”H put on a talis like a shaliach tzibbur and taught Moshe the 13 middos and said whenever Israel sins they should perform before Me according to this order (which we understand to be repeating the 13 middos) and I will forgive them. Are there any authorities who infer that for saying the 13 middos the shaliach tzibbur should wear a talis?
