In validate-with-xml-schema step, XSD file cannot import another XSD file
It looks like Saxon wants us to call net.sf.saxon.om.AttributeMap.fromList . That way it will be compatible with both 10.0 and 10.1.
I'm a bit confused by your statement regarding release dates. "The June release (rel 0.9.3.7-beta) was published on 2020-06-27." "Saxon 10.1 maintenance release for Java, released 14 May 2020."
See attached break10.xpl for the pipeline that exhibits the behavior. See attached break10.log for Morgana's output. It crashes on the <xsl:copy> because it doesn't have any attributes.
