/// These fragments are not a generic IMAP client

/// arbitrary values, only enum for which the code is known
/// to be correct. The idea is that the generated message is more
/// or less hardcoded by the developer, so its clear what's expected,
/// and not generated by a library. Also don't use vector of enum,
/// as it again introduce some kind of genericity we try so hard to avoid:
/// instead add a dedicated enum, for example "All" or anything relaevent that would
/// describe your list and then hardcode it in your fragment.
