| HTML 3.2 aims to capture recommended practice as of early '96 |
| and as such to be used as a replacement for HTML 2.0 (RFC 1866). |
| Widely deployed rendering attributes are included where they |
| have been shown to be interoperable. SCRIPT and STYLE are |
| included to smooth the introduction of client-side scripts |
| and style sheets. Browsers must avoid showing the contents |
| of these element Otherwise support for them is not required. |
| ID, CLASS and STYLE attributes are not included in this version |
| of HTML. |
