Add class to UL in toc

Hi XWiki Team,
as i don't know where to edit it i've to ask you for a favor.

The <li> tag of the toc macro got a class-Tag (tocEntry). For customizing the layout by stylesheets it would be great if the <ul> gets a class-Tag too (something like tocList).

It would be nice if you could tell me were the toc macro currently is stored, so that i am able to edit it myself, till the change is part of a release if it will be

Thanks in advance

Christoph
