Allow users to specify Project Language Level that is generated with plugin

When i run mvn idea:idea plugin, the projects are generate .ipr files with Project Language Level set to 5.0

Is there a way to configure the plugin to have that be set to 6.0 instead?

It seems that you need this attribute in the <component> declaration: languageLevel="JDK_1_6"

 <component name="ProjectRootManager" version="2" languageLevel="JDK_1_6" assert-keyword="true" jdk-15="true" 
project-jdk-name="1.6" project-jdk-type="JavaSDK" />

This is what i have after i set the language level manually, see screenshot. This is in IntelliJ 8.1
