According to the OTspec (
"edit only" option means that a font (a) can be embedded in a document and
(b) can subsequently be transiently loaded onto a system opening the
document to edit the document. That's in contrast to "can be transiently
loaded onto a system for read-only usage of the document".
I suspect that the confusion of the _ONLY label is just due to sub-optimal
naming; I don't think the specification upstream matches that, semantically.
