No, often stylesheet writers are not in control of the XML and have
to deal with what they get. If you can change it, great, but if you
cannot change it, then the stylesheet can deal with it very straightforwardly.

Not a XSL-FO issue to solve, it is an XSLT problem that can be easily resolved.

An XSLT solution is below ... I hope you find this helpful. I'll
leave the XSL-FO to you to resolve.
