The Latin Mass Society's 2010 Ordo for the Liturgy celebrated in the Extraordinary Form is published on the website of the Liturgy Office of the Bishops Conference of England & Wales.
In that Ordo one reads the following:
External Solemnity of a Holyday of Obligation in England and WalesIn Appendix 2, the following is set out:
The Bishops of England and Wales have requested that any Holyday of Obligation in England and Wales that is transferred to a Sunday in the New Rite (the Ordinary Form of the Roman Rite) should likewise be celebrated on that same day in the Old Rite (the Extraordinary Form). Subsequent to the production of last year’s Ordo a reply by the Pontifical Commission Ecclesia Dei (N107/97 20 October 2008), to a dubium from the LMS, was received. This confirmed that such an external solemnity is regulated according to the General Rubrics of the Missal (356-361). It further confirmed that it is legitimate to continue to celebrate the Mass and Office of these holydays on the days prescribed in the 1962 Calendar. The solutions in Appendix 2 have been compliled in accordance with these norms.
External Solemnity of a Holyday of ObligationThere is a contradiction between the above and the following statement which appears on the Liturgy Office's website:
Only 2 Low Masses, or 1 Low and 1 High or Sung Mass, are allowed.

Following a request for information the Bishops' Conference of England and Wales submitted a dubium to the Pontifical Commission Ecclesia Dei which confirmed that in the Roman Rite, whichever Form of the liturgy is being celebrated, the Holydays of Obligation are held in common. Where the obligation has been removed and the Holyday transferred to the Sunday, the Epiphany of the Lord, the Ascension of the Lord and Corpus Christ, this is to be followed in both Ordinary and Extraordinary celebrations of Mass.Where there is a doubt of law the law does not bind. The Liturgy Office publishes neither the text nor the protocol number of the dubium and the response. The LMS Appendix at least gives the date and protocol number of the reply to their dubium and gives details. It would appear therefore that one can celebrate either the Mass of the Sunday after the Ascension or the Mass of the Ascension.
Maybe I am being pernickety but I do feel it is important to be seen to want to obey and to take the trouble to find out what the Church permits/recommends. The attitude of some appears to imply a general disrespect for the Bishops of England & Wales which is not healthy. Now I have taken the trouble, I am content with either solution. But I daresay there will be those who would not be happy to find a priest celebrating the Ascension in the Extraordinary Form this Sunday.
