I think the complete list of domain properties includes formatDomain:
lensDomain, instanceLensDomain, formatDomain, classFormatDomain,

formatDomain expects properties or lists of properties in core. Unless
you were driving home a point just about the resource-type domain
properties, I think it makes your proposal below a bit incomplete.

Maybe propertyFormatDomain?

It doesn't quite fit with making the most used terms compact, but it is
more consistent. I can accept that.
