Clarification requested: optional parameter

[Jean-Noël Colin]

Hello,

I would like to clarify something about optional parameters: does an optional parameter have to appear, but without value, or does it have to be skipped completely, or are both options valid? 

For instance, in authentication request, if I don't want to specify a claimed_id, do I simply not include the parameter in the list, or do I include it without value?

openid.ns=http://specs.openid.net/auth/2.0

openid.mode=checkid_immediate
openid.claimed_id=
openid.assoc_handle=thisisahandle

vs

openid.ns=http://specs.openid.net/auth/2.0
openid.mode=checkid_immediate
openid.assoc_handle=thisisahandle

Best regards

Jean-Noël Colin

Optional parameters should be absent rather than empty, unless the parameter specifically indicates that an empty value is permissible.

My interpretation, and from what I've seen what people do.
