E.17.1:14.1 - Subset selection

A MultiViewDescribing use may legitimately import only a subset of a bundle’s viewpoint references. When it does so, it should declare:

• which ordinary family designator is the source,
• which viewpoint members are actually in local use,
• and whether the omitted members are simply unused or are intentionally excluded because the local scope does not require them.

The local family must not speak as if it had imported the whole bundle while silently dropping inconvenient viewpoints.
