+###############################################################
+Integration of Waffle Switch for XQueue Submission
+###############################################################
+
+Status
+******
+
+**Pending** *2025-02-11*
+
+Implementation in progress.
+
+Context
+*******
+
+In the `edx-platform` repository, there was a need to implement a mechanism that allows conditional execution of a new functionality: sending a student's response within an exercise to the `created_submission` function. This mechanism should be easily toggleable without requiring code changes or deployments.
+
+Decision
+********
+
+A `waffle switch` named `xqueue_submission.enabled` was introduced within the Django admin interface. When this switch is activated, it enables the functionality to send data to the `send_to_submission` function, which parses and forwards the data to the `created_submission` function.
+
+The `created_submission` function resides in the `edx-submissions` repository and is responsible for storing the data in the submissions database.
+
+Implementation Details
+----------------------
+
+This functionality was implemented within the `edx-platform` repository by modifying the following files:
+
+1. **`xmodule/capa/xqueue_interfaces.py`**  
+   - The `waffle switch` **`xqueue_submission.enabled`** was added here.
+   - This switch is checked before invoking `send_to_submission`, ensuring that the submission logic is only executed when enabled.
+
+2. **`xmodule/capa/xqueue_submission.py`**  
+   - This file contains the newly implemented logic that parses the student’s response.
+   - It processes and formats the data before calling `created_submission`, ensuring that it is correctly stored in the **edx-submissions** repository.
+
+Consequences
+************
+
+Positive:
+---------
+
+- **Flexibility:** The use of a `waffle switch` allows administrators to enable or disable the new submission functionality without modifying the codebase or redeploying the application.
+- **Control:** Administrators can manage the feature directly from the Django admin interface, providing a straightforward method to toggle the feature as needed.
+- **Modular Design:** The logic was added in a way that allows future modifications without affecting existing submission workflows.
+
+Negative:
+---------
+
+- **Potential Misconfiguration:** If the `waffle switch` is not properly managed, there could be inconsistencies in submission processing.
+- **Admin Overhead:** Requires monitoring to ensure the toggle is enabled when needed.
