All of those, i.e. NOT 'behaviour', and no others.

All optional except locator.

Type is per link element, locator and scheme per explicit resource
(i.e. one in (simple) links, one per locator element in mlinks);
caption and role per resource (i.e. two in links (see previous message
about name collision) and one per locator element in mlinks).

All in av-pairs.

Type: no, just a syntax, as before: a(.a)*
Locator scheme: a minimum set, not closed.
Locator: no, just a syntax per scheme, by reference to relevant standard

Implicit in answers above.
