add an id and/or a class to OL tag from toc macro

Hello,
Is it possible to add an id on <ol> tag from TOC macro?

"Example 3" from http://extensions.xwiki.org/xwiki/bin/view/Extension/TOC+Macro doesn't work because there are anothers <ol> tags on page.

If code macro generate an <ol id="toc"> by example it will be simpler to customize this TOC with StyleSheetExtension without break another <ol> tag

(I haven't found TOAC macro source on https://github.com/xwiki/xwiki-platform)
