Although ... the "official" way is as follows (leaving out anything not
directly related to the <a>):

<a href="???"><nevow:attr name="href"><nevow:slot name="linkURL"/></
nevow:attr><nevow:slot name="linkTitle">Link Title</nevow:slot></a>

The mapping renderer on your <li> will fill the 'linkURL' (and
'linkTitle') slot. The <nevow:attr> will then alter the href attribute
of the <a>.

But I prefer the attr.tac way, it's not so ugly ;-).

Cheers, Matt
