Re: [Xsltforms-support] XLSForms and XSLTForms: the default uuid() and how best to handle it

Just to add, one of the great features of XSLTForms is that it is possible
to call arbitrary JavaScript functions from XForms expressions.

Here is an updated version of your form, with a UUID function that I found
quickly on GitHub (
