Servlet 4.0 is marked as wrong attribute value in web.xml

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>4.0.1</version>
    <scope>provided</scope>
</dependency>

I've set the version of javax.servlet-api to 4.0.1, but it is marked as wrong value in web.xml.

How to I fix this?
