Ah, thanks for the clarification, Bryan. Time for me to re-read the manual,
apparently!
With the agility example from the manual, is there really any difference to
Hobo between this (the original):
<aside:>
<h2>Project Members</h2>
<collection:members part="members"/>
<form:memberships.new update="members" reset-form refocus-form>
<div>
Add a member:
<name-one:user/>
</div>
</form>
</aside:>
and this (other than being slightly more typing)?
<aside:>
<h2>Project Members</h2>
<div id="div-members">
<collection:members"/>
</div>
<form:memberships.new update="#div-members" reset-form refocus-form>
<div>
Add a member:
<name-one:user/>
</div>
</form>
</aside:>
