Ciao Enrico,

I'm not an expert on the process for adding NAPTR records to the 
uri.arpa domain, but if I recall correctly (and based on a quick 
re-reading of RFC 3405), this domain is reserved for URI schemes. 
However, there is no `lex` URI scheme, so I don't immediately see how we 
could add `lex` to uri.arpa.

On the other hand, your request to register a NAPTR record in the 
urn.arpa domain seems perfectly legitimate, since we've already added 
`lex` as a formal namespace ID in the URN namespaces registry. [1]
