The WordPress 2.3 beta tag cloud is XHTML Transitional not Strict. Also if you want to keep UTW then the permalinks /tag/sometag will not work; the /tag/ will go to the WordPress one and not the UTW version.
Hopefully someone will make a UTW like interface, presentation plugin that lets you use the built-in tag system but enjoy UTW’s tools and functions.
