Acutally, I beleive there is a difference between the two (2) terms, and a specific reason for using one and not the other in OpenJUMP. Martin Davis or Jon Aquino could confirm what I am about to say.
An "item" can refer to a feature that is part of a composite Feature or FeatureCollection. (A FeatureCollection can also be a Feature.) For example, a LineString that is part of a MultiLineString would be an "item". Check out page 14 of the old developer guide for this explanation: "FeatureSelection (in which the user has selected whole features), PartSelection (in which the user has selected parts of a GeometryCollection feature), and LineStringSelection (in which the user has selected LineStrings inside a Polygon or GeometryCollection). So a user can select not only whole features but also pieces of them." This distinction is made frequently in the source code for the selection manager. I acutally find that the use of items makes the code much more complex, but I remember Martin or Jon explaining there was a good reason for implementing the selection mechanism this way.
