Reference to external css stylesheet removed when saving as plain svg
This is a follow up report of bug #168631.
The xml-stylesheet tag with a link to a css stylesheet is removed when saving as "Plain SVG" (no problem when saving in other svg types).
For example the line from back.before.svg of the attachment :
<?xml-stylesheet type="text/css" href="default.css" ?>
is removed when saving as plain svg.
