Re: [WebIDL] Default Values for Arguments

Hi Ian,

If I understand you right, it should be enough to put a descriptive text on
the appropriate method in order to indicate what the actual requirements for
an implementation are (e.g. default value if left out)?

But then most of the implementation-relevant requirements could be put into
the interface's documentation rather than specified formally. For example,
[TreatNullAs] could also be documented informal, can't it? So if I didn't
get anything wrong, the question is which directives are specified
(in)formal?!
