[Xsltforms-support] Support for @relevant on submission

[Grégoire C. <gco...@gm...>]

Hi Alain,

Latest versions of XSLTForms are good. But what I still miss, though, is
the support of the "relevant" attribute on <xforms:submission>. Is there
something special about it? I would say it's not very different from the
"if" attribute on <xforms:action>, which work fine and are very useful
too. Is there some hidden difficulty in @relevant?

Amicalement,
Grégoire
