Hi!
Thank you for maintaining this robust HTML linter!
I'm using bootstrap-progressbar on an old project,
that uses custom HTML attributes like aria-valuetransitiongoal.
There is a minimal HTML usage example (without the JS libs):
<!DOCTYPE html>
<html lang="fr">
<head>
<meta name="generator" content="HTML Tidy for HTML5 for Windows version 5.6.0">
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Issue reproduction for HTML Tidy</title>
</head>
<body>
<div class="progress">
<div class="progress-bar progress-bar-primary six-sec-ease-in-out" role="progressbar" aria-valuetransitiongoal="80">
80%
</div>
</div>
</body>
</html>Calling HTML Tidy on this file:
$ tidy -quiet -lang en -indent -wrap 0 -modify index.html
line 13 column 5 - Warning: <div> proprietary attribute "aria-valuetransitiongoal"
Could it be possible to add an option in htmltidy.conf to ignore this kind of situation please?
I' would like the tidy CLI to exit with status 0 while validating this file.
