New PHP extension: xmldiff

Hi, some time ago i've sent a mail about the xmldiff extension, that mail can be read here http://news.php.net/php.pecl.dev/10928 . The extension is able to diff/merge XML documents. Works so far in production under linux, windows is fine according to the tests, too. Is there some interest to be that published under the PECL's hood? I could assume the silence as yes :) Just trying to get things done so far privately out here, better it's used by the world than laying around on my local HD. Thanks Anatol
