Here’s my working function, which applies itself recursively, resulting in a completely resolved map.
The only thing I had to do to my existing supporting code was update it to take a base URI parameter to account for the loss of base URIs in the process of resolving references and copying nodes during the update.
I had not actually realized there was an XQuery Update 3.0 spec, so this was very instructive.
import module namespace dutils=http://servicenow.com/xquery/module/now-dita-utils; import module namespace relpath=http://servicenow.com/xquery/module/now-relpath-utils;
declare %updating function local:resolveMaprefs($context, $baseUri as xs:string?) { let $baseUri as xs:string := if (exists($baseUri)) then $baseUri else relpath:base-uri($context) let $maprefs as element()* := $context//mapref[@href][string(@scope) ne 'peer'] return for $mapref in $maprefs let $targetUri as xs:string := relpath:resolve-uri(string($mapref/@href), $baseUri) let $refTarget as element()? := dutils:resolveReference($mapref/@href, $baseUri) let $newTarget as element()? := if (exists($refTarget//mapref[@href][string(@scope) ne 'peer'])) then $refTarget transform with { local:resolveMaprefs(., $targetUri) } else $refTarget
return if (exists($newTarget)) then let $newAtts as attribute()* := ($mapref/@* except ($mapref/@href, $mapref/@format, $mapref/@base), $newTarget/@* except ($newTarget/@href, $refTarget/@*:DITAArchVersion, $newTarget/@domains, $newTarget/@base) ) let $newAtts as attribute()* := for $att in $newAtts let $attname as xs:string := name($att) group by $attname return $att[1] let $newNodes as element() := <topicgroup class="+ map/topicref mapgroup-d/topicgroup " base="submap {$refTarget/@base} {$mapref/@base}" xml:base="{relpath:base-uri($refTarget)}" >{$newAtts} <topicmeta class="- map/topicmeta "> <navtitle class="- topic/navtitle ">{ $newTarget/*[dutils:class(., 'topic/title')]/node() }</navtitle> </topicmeta> {$newTarget/* except ($newTarget/title, $newTarget/topicmeta)} </topicgroup> return replace node $mapref with $newNodes else ()
}; let $mapurl as xs:string := 'bundle-devops-enterprise-dev-ops.ditamap' let $inputMap as document-node() := db:open('utah', $mapurl) return ( $inputMap transform with { local:resolveMaprefs(., relpath:base-uri(.)) } ,() )

This is the correct invocation:
return ( $inputMap transform with { local:resolveMaprefs(.) } ,() )
I also successfully applied the transform recursively, so I think I have, despite my best efforts, figured out how do this map resolution as efficiently as possible.
Cheers,
E.
