This is simply a matter of history, which the article sufficiently docuмents, naming the Coptic and West Syrian rite in particular, and reproducing these entire rites for easy perusal and comparison, not even theology.
Neil, well, here is the relevant portion of Anglicanorum Coetibus regarding profession of faith and ordination.
§5 The Catechism of the Catholic Church is the authoritative expression of the Catholic faith professed by members of the Ordinariate.
...
§ 1. Those who ministered as Anglican deacons, priests, or bishops, and who fulfil the requisites established by canon law[13] and are not impeded by irregularities or other impediments[14] may be accepted by the Ordinary as candidates for Holy Orders in the Catholic Church.
...
Candidates for Holy Orders in an Ordinariate should be prepared alongside other seminarians, especially in the areas of doctrinal and pastoral formation.
