What is difference between and in maven plugin (jbehave example)

As in title - here is piece of code.
I can have < scope > as well as < phase >
Jbehave documentation doesn't say much about it
(http://jbehave.org/reference/stable/maven-goals.html)
<execution>
<id>run-stories</id>
<phase>test</phase>
<configuration>
<!--<scope>test</scope>-->
<includes>
<include>**/*Stories*.java</include>
</includes>
</configuration>
<goals>
<goal>run-stories-as-embeddables</goal>
</goals>
</execution>
