    Mainly a pointer to UAX31, which is far too complex for me to understand.

    Can someone explain in few words what the proposed change will affect?
    Particularly, I cannot decide if

        avinguda Paral·lel;

    would be made an acceptable identifier of supposed type "avinguda", and if
    yes under which sets of rules (the "old, unrecommended" ones, i.e. using
    ID_Continue, and/or the "new, recommended" ones using XID_Continue)?

    Many thanks in advance.

    Also, is it possible to made additional comments regarding the form UAX#31
    is written? Particularly the use of "legacy" in paragraph 5.1; and also the
    sentence "U+00B7 MIDDLE DOT is allowed in ID_Continue", which seems to me to
    state exactly the opposite of what is exposed in the Public Review Issue
    ("U+00B7 MIDDLE DOT has [...] not the ID_Continue property", see above)...
