Section 4.1.4 says:

   Note that not all link layers use this name, and currently most EAP
   methods do not generate it.  Since the NAS operates in pass-through
   mode, it cannot know the Key-Name before receiving it from the AAA
   server.  As a result, a Key-Name AVP sent in a Diameter-EAP-Request
   MUST NOT contain any data.  A home Diameter server receiving a
   Diameter-EAP-Request with a Key-Name AVP with non-empty data MUST
   silently discard the AVP.  

It should say:

   Note that not all link layers use this name, and currently most EAP
   methods do not generate it.  Since the NAS operates in pass-through
   mode, it cannot know the name of the key before receiving it from the AAA
   server.  As a result, an EAP-Key-Name AVP sent in a Diameter-EAP-Request
   MUST NOT contain any data.  A home Diameter server receiving a
   Diameter-EAP-Request containing an EAP-Key-Name AVP with non-empty data MUST
   silently ignore the AVP.  

Notes:

In the original text, the first occurrence of the string "Key-Name" apparently is meant to refer to the actual name of the key, rather than an AVP identifier, while the next two occurrences are obviously typos, since no Key-Name AVP is defined in the document. Also, the term "silently discard" is typically used in reference to messages; with reference to a single AVP, "silently ignore" seems more appropriate.
