Correct answer: A
Answer: Yes
Why: XML is designed to be extensible, so adding new elements or attributes usually does not break existing applications.
Most XML parsers and well-designed applications ignore unknown elements and attributes unless they are explicitly required, allowing backward compatibility.
However, if an application enforces strict schema validation (for example using an XSD that disallows unknown elements), adding new data can cause validation errors and the application may reject the document.
Best practices to maintain compatibility include using namespaces, versioning, and avoiding changes to required structure.
