Custom non-editable fields within one editor?

[slawton-concurrency]

We have a use case where we need fields within one document that cannot be edited by the user.

For example:

Title: <---- Should not be editable

Enter title here... <---- Should be editable

Description: <---- Should not be editable

Enter description here... <---- Should be editable

Is this possible to do with one editor for the full document? Or do we need multiple editors on a page to achieve this?
