Add Camel schemas to XML catalog so code assistance works in XML files

I wanted to have code assistance in the XML editor, eg to press ctrl + space, to see which EIPs I can use in the editor.
I had to manually add the Camel schema to Eclipse.

Maybe we can add the schemas in the Fuse RCP distribution and/or plugin, so end user have them out of the box.
We would need both the spring and blueprint schemas.
