That was the intent. In 2007, during an informal discussion between
some of the participants of this WG, someone asked about "d=" and
"i=". The general view was to take the domain name from the "i=".
d= was more of a way to identify the DNS subtree which the public key
can be retrieved. There was also a long discussion on the mailing
list which lead to "q=". One or more participants argued for a query
infrastructure that was not DNS-based.
