PCED letter on fulfilling the Sunday obligation by attending an SSPX Mass and diocesan seminarians as subdeacons

The Polish Traditionalist Catholic blog Nowy Ruch Liturgiczny published yesterday the November 6, 2012 response of the Pontifical Commission Ecclesia Dei to two queries (which that blog reproduced in the original English): 

1. Is it possible to fulfill the Sunday obligation by participating in a Mass celebrated by a priest from Society of St. Pius X, if the participant is not "against the validity or legitimacy of the Holy Mass or the Sacraments celebrated in the forma ordinaria or against the Roman Pontiff as Supreme Pastor of the Universal Church" and this is the only opportunity in the local area to participate in the Mass in forma extraordinaria (which the participant is highly devoted to)? 

2. Do the decree of Sacred Congregation of Rites (no. 4184) and the decision of Pontifical Comission ‘Ecclesia Dei’ (no. 24/92), concerning the possibility of serving as a subdeacon during the Mass in forma extraordinaria, apply also to diocesan seminarians (who are not seminarians of the institutes erected by Pontifcial Commision 'Ecclesia Dei') who wear clerical clothing?
