Re: [Xsltforms-support] XForms, data in a repeat from a parallel instance nodeset

[COUTHURES A. <ala...@ag...>]

Jason,

Axes such as "preceding-sibling::" are not yet supported by the XPath 
analyzer of XSLTForms, which is written with XSLT 1.0.

About variables, you can create a work instance for them and use 
"xf:setvalue" to change their values.

Thank you for testing XSLTForms!
