Hello --

Somewhat to my surprise I've got the large XSLT 3.0 transform to load, or at least not complain about includes. (Load the input as a db; load the stylesheet from the file system. Be extra-careful about constructing URIs.)  Which raises the prospect that I'll actually be able to run this transform from BaseX, but I cannot figure out how to set a value for the initial template.

This query:

let $source := <dummy></dummy>

let $template :=
<xsl:stylesheet version="3.0" xmlns:xsl='http://www.w3.org/1999/XSL/Transform'>
  <xsl:template name="xsl:initial-template">
    <thingy>Hello, World!</thingy>
  </xsl:template>
 
  <xsl:template match="/">
    <fail>matched on root</fail>
  </xsl:template>
</xsl:stylesheet>
 
return xslt:transform($source,$template,map{'initial-template': '{http://www.w3.org/1999/XSL/Transform}initial-template'})

returns
<fail>matched on root</fail>

Which isn't surprising; setting initial-template is a Saxon option, not a parameter.

If I try 
return xslt:transform($source,$template,map{},map{'initial-template': '{http://www.w3.org/1999/XSL/Transform}initial-template'})

I get [XPTY0004] Unknown option 'initial-template'. (same with 'it'.)

Is there a way to set Saxon options with xslt:transform?

Thanks!
