I am kind of surprised 9.5 supports parse-xml or parse-xml-fragment and
I am not sure where the error comes from.

Does David's suggestion the XSL list to not use the
saxon:parse-pseudo-attribute function but instead throw the value of the
pi as the attribute part of an on the fly constructed element tag with
   parse-xml(parse-xml(concat('&lt;x ',.,'/&gt;'))/x/@content)
perhaps work better?
