So you'd just very simply do:
struct MyAttribute { bool activated; }
// @note is just like doing internalTuple ~= MyAttribute(true)
// and MyAttribute is of course just a plain old struct

@note(MyAttribute(true)) int a;
To check it:
foreach(note; __traits(getNotes, member_a))
static if(is(typeof(note) == MyAttribute) {
// do what you want here, ignore types you don't know
}
That's basically my initial proposal and how annotations work in Java.
What data can be packed into annotations?
Being able to use custom types is an
important part of my idea here.
I think any type that a template can take (as a value) + other
attributes/annotations.
