Re: ARIA labelledby & adopted children?

Are there any constraints  on using
<input type="text" title="Name:"/>
or
<input type="text" id="abc" />

<label class="hidden" for="abc">Name:</label>
or

<input type="text" aria-labelledby="abc" />
<span class="hidden" id="abc" >Name:</span>
I assume class=hidden is placing the span off-screen.
Is the primary intent to use WAI-ARIA to label the input field?
Thanks,
Sailesh
