Should be listed "Is property group"?

From semantic-mediawiki.org

I can try to help with this task as far as my abilities allow me. I am going to create the page to document this property, based on the Github's PR you shared. If you check the page it will be created and find some error in how it has been documented or something else, tell me to learn and solve it.
