This requiem is mentioned in:
Russell E., The Missa in agendis mortuorum of Juan García de Basurto: Johannes Ockeghem, Antoine Brumel, and an Early Spanish Polyphonic Requiem Mass. "TVNM" (29) 1979, p. 1–37
It has been noted in the recent literature that the scribe who copied Ockeghem's requiem mass into the Chigi Codex left blank openings after the offertory, possibly to accommodate a 'Sanctus', an 'Agnus Dei', and a 'communion', none of which was subsequently entered in the manuscript. No other Mass for the Dead surviving from the period lacks these three movements.
Since it is inconceivable that any liturgical service at which the Requiem was sung would have concluded with the offertory, several commentators (including this one) have assumed that either Ockeghem's 'Sanctus', 'Agnus Dei', and 'communion' were somehow unavailable to the scribe of the Chigi Codex and are now lost, or else the composer meant for them to be sung in plainchant. However, the style of Ockeghem's Requiem, as well as that of other Masses for the Dead composed not long afterwards, suggests alternative possibilities. Stylistic traits found in the so-called Missa in agendis mortuorum, for example, a compilation of movements for the requiem mass assembled by the Spanish musician Juan García de Basurto that includes the opening duo of the tract of Ockeghem's Requiem, tend to support such inferences.
NB. In the above mentioned source Basurto is called as the compiler of the Missa in agendis mortuorum. However, being a composer it is very likely that he contributed to this mass.
The requiem ascribed to Basurto is a composite work, incorporating movements from the settings by Ockeghem and Brumel; but it is unclear precisely which movements (if any) originate with Basurto himself.

His major work is the compiled Requiem mass Missa in agendis mortuorum (1525) which includes parts of
Ockeghem's and
Brumel's requiems. In 2010 the Spanish group La Capilla Peñaflorida with the Accademia Bizantina of Ottavio Dantone made a video of the agendis mortuorum for NB musika.
