In Short Message Viewer, how can you identify if a document is sliced?

A sliced document in Short Message Viewer is identifiable by a banner that explicitly indicates its sliced status. This visual cue is essential for users to recognize that the document is presented in separate segments or slices, which is particularly important for navigation and context comprehension. This feature allows users to easily discern whether they are viewing the complete document or just a part of it, facilitating a more efficient review process.

In contrast, the other options do not provide the clarity or functionality that the banner offers. For instance, while it might be true that no specific identifier exists for sliced documents in some contexts, this does not apply here since the banner serves that exact purpose. A warning message appearing when editing does not specifically convey the sliced nature, as it could relate to various editing restrictions or notifications. Finally, relying on manual checks of the interface would be time-consuming and inefficient, making it less practical compared to the straightforward visual indicator that the banner provides.
