A silverlight based website (toolkit control kit demo, SL3 version) is throwing
this exception when trying to use a regex:

System.ArgumentException: parsing
- Bad group name.

Initial inspection of the regex looks like the issue is that the first group
name is empty: (?<>.*<). It's possible that the fix is simply to allow empty
group names.
