In general, a transformer can have 1..N primary windings and 1..N
secondary windings:

The most common is the 1:1 (single primary, single secondary)
transformer, followed next by a 1:N style (one primary, multiple
secondary, this is usually used to provide plural output voltages from
the same single transformer).
But in the general case (which is what OSM would, at some point, want
to be able to cover), a transformer is N:N with each N being 1..X.
