<DIV><FONT face=Arial size=2>I do agree that we need a single place to list
these. In the past, the thinking was to list such things in the
Implementers Guide, but I'm more inclined to argue that H.460.1, perhaps Annex
A (non-existent) would be the right place.</FONT></DIV>

<P><FONT size=2>Dear experts,</FONT> </P>
<P><FONT size=2>my H.501 final draft contained a placeholder "annex B"
for collecting "generic data" (i.e. standardized GEF identifier values).
Upon advice by TSB, this annex will be removed in the published version 1 of
H.501 since it contained no useful text. </FONT></P>
<P><FONT size=2>The initial idea was to include here material from H.225.0
annex G as soon as version 2 of annex G is finished. But now I have some
doubts whether H.501 is the right place for such a data register. A
repository of generic data should at least include also values assigned in
GEF standards (H.460.x). Wouldn't the H.460 series be a better place for
this?</FONT></P>
<P><FONT size=2>At the top level we have assigned so far:</FONT> <BR><FONT
size=2>- feature ID "0" for H.225.0 Annex G profiles </FONT><BR><FONT
size=2>- feature IDs "n" for H.460.n </FONT><BR><FONT size=2>(is this the
complete list?)</FONT> </P>
<P><FONT size=2>Each top-level feature ID opens a local name space for
EnumeratedParameter-IDs specified for that specific feature. Since these are
defined locally there is no danger of collisions.</FONT></P>
<P><FONT size=2>At least the top-level IDs should be maintained at a central
place to avoid collisions, especially if such IDs can be assigned outside
H.460.n standards as well (is this generally the case, or is H.225.0 annex G
the only exception?). Of course such a repository could also list the
locally assigned EnumeratedParameter-IDs for each registered feature, to
provide a quick reference.</FONT></P>
<P><FONT size=2>So the question is, do people see the need for a
generic-data register, and if yes, in which form? H.460.x? Or in an IG?
H.501 does not seem to be the proper place.</FONT></P>
