How can I get tidy to allow my custom attributes?

Question

function myTidy($content) {
    $tidyConfig = array(
        'indent'                        => false, //don't indent
        'doctype'                       => 'omit', //don't include doctype
        'wrap'                          => 0, // don't line wrap
        'show-body-only'                => true, //don't include <html><head><title><body>
        'drop-proprietary-attributes'   => false, //this doesn't seem to be helping with our youtube stuff...
    );
    $tidy = tidy_parse_string($content, $tidyConfig, 'UTF8');
    $tidy->cleanRepair();
    return (string)$tidy;
}


echo myTidy('<span _my_custom_attr="asdfsdf">asdf</span>'), "\n";

Desired output

<span _my_custom_attr="asdfsdf">asdf</span>

Actual output:

<span>asdf</span>

What does it take to get tidy to allow my custom attribute?

I think a leading underscore make the attibute invalid, so tidy will remove it, even if your tell him not to remove unknown attributes.

Even in the SO syntax highlighter the underscore isn't hightlighted correctly :) – 2ndkauboy Jul 12 '10 at 18:37

Yep. That's what tipped me off to try removing it myself. – Frank Farmer Jul 12 '10 at 19:27

Turns out removing the leading underscore in the attribute name resolves the issue -- my_custom_attr works fine.
