For compat with existing implementations, the commandId parameter of  
execCommand() should be ASCII case insensitive.

For the formatblock command, the value parameter is Unicode case  
insensitive in IE, and ASCII case insensitive in Firefox, Safari and  
Opera. I don't have an opinion on whom to follow but it certainly  
shouldn't be case *sensitive*.

The values can also be specified without the < and > in IE, Safari and  
Opera.

Also, in IE and Opera, the formatblock command is not restricted to  
editing hosts only.
