The use of some in addition to only, is necessary because only (universal) can match to ALL values for this relation and property, and also to NO matches. The use of some further filters the classification down to those classes that DO have values for this property and relation.

Suggestion – it would be convenient if Protégé had another keyword to specify this very common classification requirement (for example a keyword onlyAndExists).
