XEP footnote Hyperlinks

Docbook-rng-5.0b4 docbook-xsl-snapshot (current) saxon-6.5.5
oxygen-7.1.0 (eclipse-3.1.2) xep-4.5

 

How does one create a hyperlink from a footnote marker to the
actual footnote in XEP transformations similar to HTML transformations?

 

Is there a stringparm that must be set?
