They sure shouldn't be!  Where are he case insensitive?

For what it's worth, the "case insensitive" parts of HTML use ASCII case 
insensitivity.  But they only apply to a limited set of identifiers. 
For anything where user-provided stuff is used, HTML is case-sensitive. 
  An exception is quirks mode, where some things like id and class 
matching for CSS are ASCII case-insensitive.

And I think (1) would be fine by me.
