I've never thought of the "openid." prefix as part of the parameter
name, even in URL form encoded messages... it's simply a namespace
prefix to ensure URL parameters don't collide. It's completely
unnecessary in KVF encoded messages, and would add nothing but extra
size to the payload.
You certainly don't need to add the prefix to KVF message to have
consistency within an OpenID library. For example, in the Internet2
library that logic is entirely encapsulated within the message encoder
and decoder. Compare URLFormCodec[0] to KeyValueFormCodec[1].
Everywhere else in the library, all message are treated exactly the
same, regardless of how they were encoded on the wire.

The only reason why one might want to use this is to include some
kind of
non-standard information. Is that something folks would want to
encourage?
Anyway, changing the spec to have "openid." there now would break
things, so
I would not recommend it unless there was a really good reason.

Subject: Re: "openid." name space of KeyValue Form
Hmmm
That's a good question. The reason we put openid.* in the request and
response is that there may be other applications sharing the same
request/response. If so, it would be more consistent if we put
openid.*
prefix to the keys of the direct response as well...
Is it just an oversight, or did it have a good reason for it?

Hello all,
I'm thinking of the good reason why "openid." name space to keys of
Key-Value Form Encoding used for direct responses is dropped.
I think that we MAY use "openid." name space.
I'm very happy if someone give me a good cue to understand the
reason.
Thanks in advance.
