Error: Unknown extension points

I'm following the instructions here

https://jazz.net/wiki/bin/view/Main/ContributingAttributePresentations

In the contributing to work item editor for web ui section.

I get the following errors in the plugin.xml

 Unknown extension point: 'com.ibm.team.workitem.service.editorPresentations'

And

Unknown extension point: 'com.ibm.team.workitem.web.editorToolbarAction'

Have these extension points been renamed to something else?

Will it resolve on its own once deployed to the server?

Thanks,

Dan
