Syntax & Structural Verification Process

The validation engine performs lexical analysis against the formal grammar, schema definitions, or RFC requirements of the format. It verifies bracket matching, character encoding integrity, required attribute existence, and delimiter consistency. If an anomaly is found, the validator pinpoints the exact line and column location alongside an actionable explanation of the syntax violation.
