Limit content in explanatory notes #45

Closed delcada closed 5 years ago

"Limit content expresses those things that were either identified at a later point to be included, clarify decisions based on specific cases, or are otherwise clarifications of “gray” areas. Notes containing any arbitrary decisions fall into this type of limit content. "

I do not agree with these sentences. Between two revisions of a given classification, classification decisions (aka caselaws or rulings) are generally kept distinct from the normal explanatory notes (see picture below) and there is a property for this: xkos:caseLaw.

The limit content case is as pure a property as the inclusion and exclusion ones. This property contains cases where decision was made on the basis of consensus or compromise because the good concerned could logically belong to two distinct categories of the classification. A very well-known example concerns wooden shoes: they can be considered either as shoes or as handicraft. In the beginning of the twentieth century they were classified as shoes; nowadays they are classified as handicraft. This is a typical example of a "limit content" case.
