No, but below in a nutshell is the basic strategy. There are two basic
functions: rend:main(), which would be called on the outermost node you
need to process (it could be a document node, a root element, whatever),
containing all the typeswitches; and rend:recurse(), that is mostly just
a way to let you say
<p>{rend:recurse($node)}</p>
rather than
<p>{for $n in $node/node() return rend:main($n)}</p>
within the typeswitch.
For simple cases, you can put the transform right in the typeswitch. For
other cases, each typeswitch calls a custom function that is more or
less equivalent to an XSLT template matching the element. Logic can be
put within the typeswitch statement or pushed off onto the custom
functions as suits you.

define function rend:main(
$content as node()*
) as node()* {
for $node in $content-new/node()
return typeswitch($node)
case element(simple) return <newName>{rend:recurse($node)}</newName>
case element(complex) return rend:complex($node)
case element(moreComplex) return
if ($something) then rend:moreComplex1($node)
else rend:moreComplex2($node)
default return rend:default($node)
}
define function rend:recurse(
(: just recurses back to rend:main() :)
$node as node()
) as node()* {
(: live code actually does various stuff here before
it recurses :)
rend:main($node)
}
define function rend:complex(
(: example of 'template' function :)
$el as element()
) as element() {
element complex {
attribute xml:id { $el:id }
attribute class { $el/@type }
rend:recurse($el)
}
}
(: etc. :)
