Hi Alain, no need to apologise. Thank you for the reply. I had never thought to try that approach. I will give it a try. Just as a matter of interest, is that a standard in the xforms spec. or is it an XSLTForms particular extension ? Thank you for all your continuing hard work on XSLTForms. Long may it (and you) continue :-) Regards Habs On 29 June 2016 at 17:59, Alain Couthures <ala...@ag...> wrote: > Hello Habs, > > Sorry for the delay.
