The generic RCDATA element parsing algorithm puts the tokenizer into the 
RCDATA state, from which the only possible tokens are text tokens, end tag 
tokens, and end-of-file tokens. These are the same tokens that the "text" 
mode handles.

So you parse a <title> start tag token, you go into "text" mode, then you 
get six character tokens, which get inserted into the <title> element, 
then you get an EOF token, and you unwind the parser and end.

What token are you getting that isn't handled?
