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
