Aha, in this case your approach should work. Would it be possible that local:get-name-predicate() returns something (not '' or ()) even if the parameter is empty?

Without local:get-name-predicate, your example does return what I expect:

xquery version "3.0";
declare namespace tei="http://www.tei-c.org/ns/1.0";
let $name-predicate := request:get-parameter('people','')
let $place-predicate := request:get-parameter('place','#snelston')
let $selected-documents :=
if($name-predicate) then 
(collection('/db')//tei:persName[@corresp=$name-predicate])
else if($place-predicate) then 
(collection('/db')//tei:placeName[@corresp=$place-predicate])
else
()
return
$selected-documents
