They are the shortname serial numbers.  Did you ever read the message
that started this thread?  Here's the proposal again:

   Each SRFI will have a title and a shortname.  Just as with the
   title, the shortname is chosen by the author, and may change during
   the revision process.  The title may be any latin-1 string (as
   now), and the shortname may be any r5rs identifier (a
   case-insensitive string in a subset of ascii as described in r5rs
   section 7.1.1).  When a SRFI is finalized, it is assigned a
   shortname serial number: the lowest positive integer that has not
   been assigned to any previous SRFI with the same shortname.

   Any srfi may be unambiguously and concisely referred to in
   announcements, manuals, papers, other SRFIs, etc., as "SRFI n",
   where n is the SRFI number, or as "SRFI shortname-m", where m is
   the shortname serial number.  Systems that support SRFIs 0 or 7
   should allow srfi-n or srfi-shortname-m as feature identifiers for

I have to wonder if perhaps this is because you haven't been
thoroughly reading the messages to which you respond.  I recommend,
again, that you try re-reading the archive.

And I still think these are the same issue.  We have a unique name
(the SRFI number) that can be used in programs and in documents to
concisely refer to a particular SRFI.  What I would like is an
alternate, easier-to-read-and-remember name, that can be used in
exactly all those contexts that the numbers are used now.

I'm not suggesting that a library system would need to support the
name string-lib as the name for a library that implemented SRFI 13.
I'm only suggesting that if a system allows you to refer in some way
to SRFI 13 with the identifier srfi-13, that it should also allow you
to refer to it as srfi-string-lib-1.  Note the "srfi-" prefix.  I
don't see how this is infringing on names likely to be used by rnrs or
by your own code.

Really, all I'm suggesting is that the names for distinguishing SRFIs
from one another be drawn from a slightly richer character set than
just #\0, #\1, #\2, #\3, #\4, #\5, #\6, #\7, #\8, and #\9.
