agreed, does it get too complicated if you write: "A locator is a name that has topological sensitivity and that must change if the point of attachment (at the layer the locator refers to) changes" ? not sure myself, the definition gets a bit complicated, but I think it is important to note that changing points of attachment on one layer don't necessarily mean changing locators at another.... > > > >>> identifier An identifier is the name of an object; identifiers have no >>> topological sensitivity, and do not change, even if the >> >> "do not change" -> "do not have to change"? > > > Sure.

Right, that was my reasoning too, without the "do not have to" readers may presuppose persistence.
