Document Ownership
The document owner is the only person with the right to alter the document.
Non-Owners should not alter the document.
Non-Owners can add comments in the comments section (if available).
Current Implementation
Trac does not support document ownership.
This means that team members with access rights should have the discipline to respect document ownership.
You will find the Document Ownership entry at the end of a document
Rationales
