It doesn't need to, that isn't what it is looking for. Try reading the 
reference I gave you:

Correct, but that isn't the issue here. I could say:

"Pull the red lever dwon"

You don't need to know what the lever does to know that 'dwon' isn't a 
word in English and that it should be 'down'.

Nothing except the HTML specification.

The problem is with the &, not with a-zA-Z, did you read the resource I 
gave you earlier?
