Hi,

Using BaseX 9.7.1 and saxon9he-9.9.1.jar

The documentation suggests the ?result from xslt:transform-report should be a document-node where possible [1]

This seems not quite to be the case when there are processing instructions or comments at the top level. In these cases a sequence of document-nodes is returned.

let $xslt:=<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="3.0">
<xsl:mode on-no-match="shallow-copy"/>
</xsl:stylesheet>

let $xml:=document{ <?something type="compact"?>, <foo/>}
return xslt:transform-report($xml,$xslt)

Returns

map {
"messages": (),
"result": (<?something type="compact"?>, <foo/>)
}
