### 13.16.1 Understanding limitations of W3C validation

Mif2Go can produce many varieties of HTML, including some that are intended for use with older browsers such as Netscape Navigator 4.x. Some default settings allow such back-compatible code generation, which does not validate to HTML 4 specifications. Also, one particular HTML tag is not accepted by W3C, certain table anomalies in your FrameMaker document can cause validation errors, and several high-ASCII characters cause validator warnings.

If you require clean validation for your output, you might have to make some adjustments to your FrameMaker document and to your configuration settings.
