Hi,

I have recently been using xslt:transform-report to get xsl:message reports.
I am using BaseX 10.7 with various versions of Saxon-he. I have run example 4 from[1]
with
Only saxon-he-10 captures the messages for me. (although when using BaseX 11 I seem to recall only Saxon 12 captured them)
Is this correct and expected?

I understand the Saxon API may be a moving target. 
Perhaps the documentation could indicate a recommended Saxon version for a given BaseX version, rather than "For the moment, messages can only be returned with recent versions of Saxon."
I have made minor updates to [2] to this effect. Please edit or revert if my understanding is incorrect.

I agree it's somewhat unexpected. As we are working on the string result that is returned by Saxon, it's currently not that easy indeed to decide how to interpret the character stream.

Ok thanks. I thought this might have been unintended behavior.
if($report?result instance of document-node()+) then document{$report?result} else $report?result
seems to give me what I expected here.

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/>)
}
