I can't open a script with the next code:

xml code:

---

<?xml version="1.0" encoding="utf-8"?>
<ScriptInfo xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="urn:msgplus:scripts">
    <Information>
        <Name>Test</Name>
        <Description>Testing</Description>
        <Version>1.0.3</Version>
    </Information>
</ScriptInfo>

---

what's wrong?
