I think this kind of thing is usually done using peek rather than taking an alternative branch if parsing fails. I'm not sure what this code would do on unexpected input (i.e. tokens that are none of [attribute, request_ke]).

This works let attributes = input.call(Attribute::parse_outer)?;
I was wondering about not advancing the "cursor" and stuff I originally did have peek, but the syn docs say to use .call for attributes but now it will fail when it's supposed to I think.
