MUST? In for example mobile networks the layer 3 locator often doesn't

a locator refers to layer 3 by default.
Ok, but in a mobile network, it's usually the L2 point of attachment
that's changing, not the L3 point of attachment. When you do change
that (i.e., roaming), then your locator is indeed changing and all sorts
of registration mechanisms are in place to update your locator.
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. Someone might want to change their identifier at the time that
they roam for privacy reasons. That's certainly reasonable.
Thanks,
Tony
