Disallow an element name in entire XML document using XSD

I am using XSD files to validate some XML files. One rule is that no script is allowed in the xml or specifically in this case xhtml document. I reckon that we need to specify in XSD file that no tag name = "script" is allowed in the entire document. How can this control be achieved?

As a beginner is XSD world I tried 

      <xs:element name="script" maxOccurs="0"/>

but apparently it doesn't work.

XSD 1.0

You cannot directly express the constraint that no script element may exist in the document, but you can omit script and allow it no way in: Simply do not use it in any the content models of any elements, and do not use xsd:any with lax or skip for @processContents.

XSD 1.1

In XSD 1.1 you can use xsd:assert to restrict xsd:any[@processContents='strict'] further (anywhere xsd:any is needed, or even for entire contents of the root element):

<xs:assert test="every $e in .//* satisfies $e[not(self::script)]"/>
