CherryPy implements that (since "opaque-tag = quoted-string"). Granted,
it's a small project, but when I implemented RFC2047 decoding, that was
the only "reasonable reading" I arrived at. I must have glossed over the
"octet equality" clause for ETag at the time. :/

Sounds reasonable. Perhaps the phrase "A string of text is parsed as a
single word if it is quoted using double-quote marks" needs some
elaboration as well.
