<p>The 'experimental' Nu Markup Checker flags this as an <strong>HTML5 ERROR</strong> with the string <strong>
|
||
|
|
"Error: The center element is obsolete. Use CSS instead."</strong>
|

|
|
</p>
|

|
|
|

|
|
<p>If 'clean' at present tidy 'silently' replaces this with a <div class="c1">, and
|
||
|
|
add the CSS in TY_(CleanDocument)(doc), ...

|

|

|
|
<p>Q: <strong>Should this behaviour be modified?</strong>
|
||
|
|
</p>
|
||
|
|
<p>A: There are various possibilities<br>
|
||
|
|
<ul>
|
||
|
|
<li>If the document is configured (or found?) to be HTML5, then
|
||
|
|
<ul>
|
||
|
|
<li>If clean configured
|
||
|
|
<ul>
|
||
|
|
<li>Fix it silently, <strong>as now</strong>
|
||
|
|
<li>Fix it with a warning
|
||
|
|
<li>No fix and flag as an error, like the validator
|
||
|
|
</ul>
|
||
|
|
<li>Clean not configured
|
||
|
|
<ul>
|
||
|
|
<li>No fix, with no warning or error, <strong>as now</strong>
|
||
|
|
<li>Fix it with a warning
|
||
|
|
<li>No fix and flag as an error, like the validator
|
||
|
|
</ul>
|
||
|
|
</ul>
|
||
|
|
<li>Else if NOT configured (or found?) to be HTML5
|
||
|
|
<ul>
|
||
|
|
<li>If clean configured
|
||
|
|
<ul>
|
||
|
|
<li>Fix it silently, <strong>as now</strong>
|
||
|
|
<li>Fix it with a warning
|
||
|
|
</ul>
|
||
|
|
<li>Clean not configured
|
||
|
|
<ul>
|
||
|
|
<li>Flag as a warning
|
||
|
|
<li>Flag as an error
|
||
|
|
<li>No warning or error, <strong>as now</strong>
|
||
|
|
</ul>
|
||
|
|
</ul>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p>Also perhaps Tidy5 needs another configuration parameter as suggested by the validator.w3.org,
|
||
|
|
namely <strong>"HTML4-specific tokenization errors are enabled."</strong> That is being
|
||
|
|
able to clearly inform tidy that is the document is to be taken as HTML5, then certain
|
||
|
|
tags are to be an error.
