Another workaround would be to use the XSLT implementation the XSLT 3
spec supplies i.e. given in
https://www.w3.org/TR/xslt-30/#xml-to-json-stylesheet and given at
https://www.w3.org/TR/xslt-30/xml-to-json.xsl.

At least for me with Saxon-JS 2.3, doing

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
   version="3.0"
   xmlns:xs="http://www.w3.org/2001/XMLSchema"
   exclude-result-prefixes="#all"
   xmlns:j="http://www.w3.org/2013/XSLT/xml-to-json"
   expand-text="yes">

   <xsl:import href="https://www.w3.org/TR/xslt-30/xml-to-json.xsl"/>

   <xsl:template match="/*">
     <processor-xml-to-json>{xml-to-json(., map { 'indent' : true()
})}</processor-xml-to-json>
     <spec-xml-to-json>{j:xml-to-json(., map { 'indent' : true()
})}</spec-xml-to-json>
   </xsl:template>

works to give e.g.

<processor-xml-to-json>{"name":"XML","value":"unlimited"}</processor-xml-to-json>
<spec-xml-to-json>{"name" : "XML",
      "value" : "unlimited"}</spec-xml-to-json>

so the function is usable and does some job of indentation.
