“There is no such thing as an invalid annulment as claimed by the schismatic SSPX (and/or others) who are not in Communion with the Church. Please! The Vatican has NOT declared sspx to be schismatic - therefore YOU are not free to do so.”
Yes you have a point, they are not formally in schism since the lifting of the excommunications, but are materially. They are not in full communion with the Church.en.wikipedia.org/wiki/Society_of_St._Pius_X#Canonical_situation

3. In itself this act was one of disobedience to the Roman pontiff in a very grave matter and of supreme importance for the unity of the Church, such as is the ordination of bishops whereby the apostolic succession is sacramentally perpetuated. Hence such disobedience–which implies in practice the rejection of the Roman primacy–constitutes a schismatic act. [Code of Canon Law, 751.] In performing such an act, notwithstanding the formal canonical warning sent to them by the cardinal prefect of the Congregation for Bishops last June 17, Archbishop Lefebvre and the priests Bernard Fellay, Bernard Tissier de Mallerais, Richard Williamson and Alfonso de Galarreta have incurred the grave penalty of excommunication envisaged by ecclesiastical law. [Cf. Code of Canon Law, 1382.]

b. Thus far the Church has not officially declared what Constitutes “formal adherence to the schism” inaugurated by the late Archbishop Lefebvre (cf. Ecclesia Dei 5, c), but the Code of Canon Law defines schism as “refusal of submission to the Roman Pontiff or of communion with the members of the Church subject to him” (canon 751).
d. We reiterate what we stated above: “The Pope is the Supreme legislator in the Church.” Communion with him is a fundamental, non-negotiable hallmark of Catholicism which is not determined by those who set themselves up to judge him, but by the Pope himself (cf. Second Vatican Council’s Dogmatic Constitution on the Church Lumen Gentium #22-25)."
** In his letter of 10 March 2009 concerning his remission of the excommunication of the four bishops of the Society of St Pius X, Pope Benedict XVI declared: “Until the doctrinal questions are clarified, the Society has no canonical status in the Church, and its ministers - even though they have been freed of the ecclesiastical penalty - do not legitimately exercise any ministry in the Church.”**
