> if this is correct?
It's correct. The normative spec for what calling a constructor does is at
http://heycam.github.io/webidl/#es-interface-call and directly invokes "convert
to an IDL value" on the arguments. This will throw for an invalid value of an
enumeration.
> and for attributes assigning an invalid value is *ignored*.
This is done explicitly in http://heycam.github.io/webidl/#dfn-attribute-setter
which doesn't actually invoke "convert to an IDL value" in the enumeration
case.
> as constructors set *attributes*
Not as far as WebIDL is concerned. Any attribute setting a constructor might
do would happen in the "performing the actions listed in the description of
constructor with values as the argument values" step (step 5 in the "The
internal [[Call]] method of the interface object behaves as follows" steps,
which I sadly can't link to directly), while the handling of the constructor
arguments happens in step 4 of those same staps.
