Looks good, but do you expect the last sentence to be exhaustive, or are those just examples?

On a quick search, it looks like that's at least discussed (and maybe defined) in ITU-T P.800.

In this document we used the more informal term "probe", as it seems easy to understand without a formal definition. Since this use cases doc might have a wider readership, we wanted to avoid terminology and just give the reader the motivations and usages of LMAP measurement information.

Could you offer an informal definition, or a "such as [example]" sort of thing? "Probe" has many meanings. Context might be enough for some readers, but possibly not all.
