Subject: RFC 4570 errata

Hello,
in the recently published RFC 4570 (SDP Source Filters)
authored by you, I found a couple of textual flaws that
might be corrected by posting an RFC Errata Note.

(1)  punctuation

Text in Section 1 does not conform to the "rational quoting"
style generally followed in technical/mathematical documents
and stated in all RFC authoring guides.

The second paragraph on page 2 says:

                               [...].  Applications and hosts may also
   share the source-filter information with network elements (e.g., with
   routers using [IGMPv3]) so they can potentially perform the traffic
|  filtering operation further "upstream," closer to the source(s).
                                        ^^

It should say:

                               [...].  Applications and hosts may also
   share the source-filter information with network elements (e.g., with
   routers using [IGMPv3]) so they can potentially perform the traffic
|  filtering operation further "upstream", closer to the source(s).
                                        ^^

(2)  typos (grammar)

The second paragraph of Section 4, at the bottom of page 8, says:

                              [...].  Use of source-filters do not
   corrupt the ASM semantics but provide more control for receivers, at
   their discretion.

It should say:
                                                              vv
|                             [...].  Use of source-filters does not
|  corrupt the ASM semantics but provides more control for receivers, at
   their discretion.
                                        ^

The issue becomes even more apparent when the article is added, as well:

|                             [...].  The use of source-filters does not
|  corrupt the ASM semantics but provides more control for receivers, at
   their discretion.

(3)  improper text in IANA registration template

The filled out SDP attribute registration template in the IANA
Considerations (Section 6) on page 10 contains improper wording
-- either just being garbage (there are no 'registrations below'
in the RFC), or getting inappropriate when extracted from the RFC
and included in a stand-alone IANA document.

At the end of the template, the RFC says:

|       Purpose:            See this document
|       Reference:          This document
|       Values:             See this document, and registrations below

It should say:

|       Purpose:            See RFC 4632
|       Reference:          RFC 4632
|       Values:             See RFC 4632

Please comment.

Preferrably, to address these issues, you should prepare an
Author's Errata Note for RFC 4632, making freely use of the
material presented above, and submit it to the RFC Editor
for publication on the RFC Errata web pages.

Best regards,
  Alfred Hönes.
