Section 2.1 says:

     Prefer: Lenient

It should say:

     Prefer: Handling="lenient"

Notes:

"Prefer: Lenient" is a valid header that specifies an (unregistered) preference named "lenient" with an empty value.

On the other hand, this document defines a preference named "handling", which can take the value "lenient" to indicate lenient processing, which is the stated intent of this example.

There is no provision for specifying a preference by its *value*, as opposed to by its *name*.
