Yes, but then Jonas replied saying that Mozilla wasn’t intending on
using them as is.  But if you are, …

All right.  To me, having an intrinsic type called ‘DOMString’ seems
kinda weird.

find . -name \*.idl | xargs perl -i -pe s/\<DOMString\>/string/g

But OK.  By the way, do you use DOMString as an intrinsic type, or do
you use a sequence<unsigned long> boxed valuetype (as defined in DOM
Core)?


I can easily rename the type back to DOMString.  I’d like to know if you
all think there is any problem in keeping the name as DOMString but
removing the null from its set of values, and requiring the use of the
nullable type ‘DOMString?’ to specify a string type that does allow
null.  Because then it is different from the traditional DOMString as
defined in DOM Core.
