Moving namespaces extension point?

- id: org.springframework.ide.eclipse.beans.ui.namespaces 

Results from extension point search:

org.springframework.ide.eclipse.beans.ui.namespaces - org.springframework.ide.eclipse.batch
org.springframework.ide.eclipse.beans.ui.namespaces - org.springframework.ide.eclipse.beans.ui
org.springframework.ide.eclipse.beans.ui.namespaces - org.springframework.ide.eclipse.data.core
org.springframework.ide.eclipse.beans.ui.namespaces - org.springframework.ide.eclipse.integration
org.springframework.ide.eclipse.beans.ui.namespaces - org.springframework.ide.eclipse.security
org.springframework.ide.eclipse.beans.ui.namespaces - org.springframework.ide.eclipse.webflow.ui

If we move extension point to xml.namespaces plugin, the id will change
and each of the references has to be changed.
