Possible bug in Build a Survey Form

I think one instruction to Build a Survey Form is a bit confusing.

User Story no. 13 states:

Inside the form element, I can select a field from one or more groups of radio buttons. Each group should be grouped using the name attribute.

While the test case states:

“All your radio-buttons must have a name attribute”


“All your radio-buttons need a value attribute”

The test does not pass if the “value” attribute is not there, and the user may not understand what is wrong, since this particular requirement is not mentioned in US#13, as opposed to US#14:

Inside the form element, I can select several fields from a series of checkboxes, each of which must have a value attribute.
