Form <inpu> name & id required?

[Caversham]

I notice that Dreamweaver automatically adds both name and id
attributes to form input tags. Are both of these required? Is there
some recommendation both should be used?

The name attribute is used when submitting the name=value pairs. The id
attribute is useful for referencing from other places, such as with the
for attribute in the label element, with scripts by using
getElementById(), with stylesheets using the ID selector, etc. Neither
of them are required.

name is for backward compatibility with legacy browsers, like NN4x.

Not for form elements. Try
<form ...>
<input type="text" id="foo" value="bar"> <input type="submit">
</form>
and see if it works :)
ID and name have different semantics and uses, like Lachlan explained.
