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)...
