Hi,
I have a problem with an xml file.
I am trying to develop an xml file based on vra core 4.0 but when I check if my code is valid I take
the following error.

Could not open file: http://www.vraweb.org/projects/vracore4/vra-4.0-restricted.xsd
(I use XML COPY EDITOR)

A part of my code is :

<?xml version="1.0" encoding="UTF-8" ?>
<vra xmlns="http://www.vraweb.org/vracore4.htm"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.vraweb.org/vracore4.htm http://www.vraweb.org/projects/vracore4/vra-4.0-restricted.xsd">
.........
</vra>

Thanks in advance
