Hi,
Are you using Oxygen desktop (installed on premise) or Oxygen WebAuthor (in-browser XML editor)?
If you are using Oxygen desktop, do you want to prohibit editing the attribute in the Text (XML view) or Author visual editor?
With what XML vocabulary are you working? DITA, DocBook, something else? Have you created a framework customization for your XML vocabulary?
