We characterize focal Borel probability measures as those Borel probability measures that are strictly positive on every nonempty open subset. We also prove the existence of focal Borel probability measures on compact metric spaces.

The same holds for countably many factors. (For uncountably many factors of at least two points each, the product is not countably separated, therefore not standard.) A measurable subset of a standard Borel space, treated as a subspace, is a standard Borel space. WebEvery subinterval is a Borel set on its own accord.
