SKiCal component property extension - PROMO

["Greg FitzPatrick" <greg.fitzpatrick@xxxxxxxxxxxxx>]

While preparing the submission of the SKiCal PROMO property, I ran into a
little trouble and I wonder if anybody can help me out?

The idea with PROMO is that it would help to keep promotional verbosity
under control by keeping advertisements in appointed places so that clients
could decide themselves if they wanted to pull down 30 second commercial to
their PDAs and so on.

We based PROMO on ATTACH, which is basically a URI place holder. Looking
again at ATTACH it appears to me that there is no method for describing what
the attachment actually contains.  Though you can say what type of
attachment it is - you can not say "what it is about".

In the 2445 examples this is not readily apparent since the URIs exemplified
use self explanatory names like;

ATTACH:http://xyz.com/public/quarterly-report.docor

FMTTATTACHYPE=application/postscript:ftp://xyzCorp.com/pub/
      conf/bkgrnd.ps

We surely cant count on this always being the case.  In the example below
the DESCRIPTION is used to solve the problem, but that seems not to be a
good approach - certainly not in the interest of promoting machine
understanding;

DESCRIPTION:A draft agenda needs to be sent out to the attendees
       to the weekly managers meeting (MGR-LIST). Attached is a
       pointer the document template for the agenda file.
     ATTACH;FMTTYPE=application/binary:http://host.com/templates/agen
      da.doc

It seems what is missing is the altrep mechanism, which gives both the URI
and a textual representation of what is to be found at that URI, but altrep
is not given as a value option for ATTACH.

Any comments?

btw. Erik there is a 2445 typo in that last example .. a pointer (to) the
document..
