Thread: Re: [Xsltforms-support] unpredicatble submission behaviour

Hi,

Sorry, AVT for XForms submission is not supported in XForms 1.1 and 
XSLTForms, use resource sub-element instead: 
http://www.w3.org/TR/xforms11/#submit-resource-elem

XPath 2.0 is not supported either, BTW, but there is the choose() 
function: http://www.w3.org/TR/xforms11/#fn-choose
