On a separate topic, I'm not sure that the second paragraph of
the Introduction is correct. Historically (sic) and as far as I
am aware, DDDS has been used heavily only in conjunction with
ENUM. It also takes me three or four readings each time I
encounter it to figure out what "looking up URIs given a
hostname" means (noting that, for some versions of DNS
terminology, a hypothetical domain (owner, node) with only NAPTR
records is _not_ a "hostname"). Perhaps something more like the
following would be both more true and easier to understand:
Historically, uses of the DNS to map a domain name to a
URL have relied on the NAPTR RRTYPEs and then on the
DDDS[RFC3401] application framework with the DNS as a
database as specified in RFC 3404 [RFC3404].
Thanks.
The following sentence isn't clear, which doesn't help.
Probably what is intended more like:
Among the implications of that usage are inability to
select interesting and relevant NAPTR records from those
that match the query.
What about:
Historically, uses of the DNS to map a domain name to a URL have
relied on the NAPTR RRTYPEs and then on the DDDS [RFC3401]
application framework with the DNS as a database as specified in RFC
3404 [RFC3404]. This has a number of implications such as the fact
the RRSet returned will contain all URIs "connected" with the owner,
and not only the ones related to a specific service.
There are several other editorial issues (e.g., "Querying for
URI resource records is not replacing querying..." later in the
Introduction and "Applications MUST know the specific service to
prepend..." in Section 3 (one cannot prepend "a service", only
an identifier of one)), but I hope we can leave them to the RFC
Editor to identify and sort out.
Yeah, as you know John, my english is not the best... :-(
Finally, given these discussions, I believe the Acknowledgements
section probably needs review and updating.
Now:
8. Acknowledgements

services exists for this domain name" and "What is the URI for this
service" came from Scott Bradner and Lawrence Conroy. Other people
