Hi Ted,
you are definitely right in thinking that SaxonHE supports integrated extension functions.
And I am very eager to get a recipe for how to use integrated extension functions in a command line interface context. It is something I have always wanted to know, but never dared to ask. Thank you for starting the thread!
Kind regards,
