[whatwg] what use-case is there for the name-attribute on a fieldset?

[Evert Van dansen]

Hello,

Recently I noticed that HTML5 allows the name-attribute on a fieldset. This was 
not the case in HTML4.0.1.
I did some tests and noticed that this name is *not* part of the POSTed data 
when submitting a form? So I was wondering when and for what purpose this 
name-attribute should or could be used?

Thanks.
