They are not equivalent: 'A B "" C D' is a list of 5 tokens. The third one contains 2 characters " and ".

The specification says this about ES: Used in whitespace separated lists when empty string is one of the values. Recall that in XML an attribute’s value may be delimited by either double or single quotes. So, are these two whitespace-separated lists equivalent? "A B %ES; C D" 'A B "" C D' /Roger
