Re: [Xsltforms-support] XSLTForms and SVG

[Alain C. <ala...@ag...>]

Tim,

This is a tricky issue because everything sounds OK from the debugger 
point of view.

Happily, changing the identity template for attributes just into 
"<xsl:copy/>" instead of "<xsl:attribute..." appears to be working for 
this testcase.

Thank you for your feedback!

Alain
