Not sure where I saw this, but I thought attributes for custom directive
could be made optional with a ?.
For example, I could have this in my directive definition object:
scope: {
foo: '@',
bar: '@?'
}
I would expect that all uses of this directive must have the foo attribute,
but the bar attribute is optional.
However, it seems that the ? has no effect and both attributes are
optional. What am I misunderstanding?
