requirePluginVersions.html has non-working example

The example on this page:
http://maven.apache.org/enforcer/enforcer-rules/requirePluginVersions.html

has this for the plugin being used:
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-enforcer-plugin</artifactId>
<version>1.0</version>

but that version doesn't exist, leading to much frustration when trying to figure out why things don't work. Please update that to whatever the current version is, or remove the version element entirely.

If the version element is being removed, it should probably be removed from the examples on other pages too, like:
http://maven.apache.org/enforcer/enforcer-api/writing-a-custom-rule.html
and any other that might have it.
