Possible disadvantages of W3C Markup Validation Service

• Limited to Syntax
  The validator primarily checks for syntax errors and does not assess other vital web development aspects such as design or functionality.
• Outdated Standards
  The tool relies on W3C's standards, which can sometimes lag behind real-world usage and popular web development trends, potentially limiting its relevance.
• Overly Strict
  The validator can be overly strict, flagging non-critical issues that may not impact user experience but are still considered 'errors' by the tool.
• Misinterpretation of Results
  Less experienced developers might misinterpret the validator's results, focusing too much on achieving perfect validation without understanding the real impact on usability.
• Lack of Support for Modern Frameworks
  As a markup validator, it might not fully support or correctly evaluate modern JavaScript frameworks that generate markup dynamically.
