It's there because:
* it was developed for the WYSIWYG editor which is the only module
relying on it so far and
* it depends on the old XWiki core to lookup components, specifically
com.xpn.xwiki.web.Utils.getComponent(Class), so I couldn't move it to
one of the new component-oriented modules
* I hesitated to move it to the old XWiki core because the current
practice is to move things out of the core not in.
Since you don't have to depend on the WYSIWYG editor module to be able
to use it we can keep it where it is for now.
Thanks,
Marius
