Dear Alain,

Do you see why <http://www.agencexml.com/xsltforms/flags.xml> gives an error with WebKit browsers?

Best,

Jens

> Hello,

> I have recently embedded XForms controls within SVG images to 
> dynamically render data.
> 
> For chart axes, I needed a repeat group based on numbers not on nodes so 
> I added an extension to XSLTForms: repeat/@from, repeat/@to and 
> repeat/@step. The loop index can be obtained with the "." XPath 
> expression so the context is not in any model and the instance() 
> function has always to be used when referring to nodes.
> 
> For pie charts, I needed trigonometric functions, which are only 
> available in XPath 3.0, but are already supported by XSLTForms.
> 
> For performance, I used an intermediate instance with calculated 
> bindings. I might have implemented the new 'var' element but initially 
> get confused with the 2.0 specs whether vars were limited to function 
> bodies or not.

> controls within text elements. I am not sure that labels in XForms group 
> controls can easily be rendered in SVG.
