Re: [Xsltforms-support] Output image/svg+xml

[Grégoire C. <gco...@gm...>]

Hi,

I think I understand what the "data:" scheme is about (never used it
before). I thought the "ref" attribute was used to resolve an URI (just
like with <output mediatype="image/jpeg">), but it seems that, in the
case of "image/svg+xml", XSLTForms uses this attribute to get an «SVG
instance». Am I right?

If so, is there a way to display a non-embedded SVG file whose URL is
computed by XForms?

Thanks!
Grégoire
