>             Project: Shindig
>          Issue Type: Bug
>          Components: Javascript 
>    Affects Versions: 1.1-BETA5
>            Reporter: Paul Lindner
>
> If you have a opensocial template library like this:
> <?xml version="1.0" encoding="UTF-8"?>
> <Templates xmlns:ext-li="http://www.linkedin.com/ext-li">
>   <Namespace prefix="ext-li" url="http://www.linkedin.com/ext-li"/>
>   <Style>
>     large-font: {
>       font-size: 20px;
>     }
>   </Style>
>   <JavaScript>
>     function global(a) {
>       a.innerHTML += 'global';
>     }
>   </JavaScript>
> ....
> And the style is invalid, then you will end up with DOM error 12 due to invalid CSS.  
> In the case above there is an extra colon between the selector and the style  'large-font : ....'
> We should catch this condition, log it, and soldier on..
