I'd rather see a simple

<live /> or <live-delayed />

flag in the XMLTV data, than

<tape-delay>live<tape-delay> or <tape-delay>delay<tape-delay>

<live /> is cleaner (IMO), easier to read, and easier to program against.

(I'm not sure about any proposed implementation details for
tape-delay, so I'm guessing here. It could be less noisy.)

Across all grabbers, I'd imagine the overwhelming majority of
programmes using these new flags would specify the "live" flag to
specify a real "live" transmission.

Here in the UK some programming that has had a known live-delay are
Formula 1 races where the broadcaster has not had the right to air the
race live, and repeats of live material on the BBC's Red Button and
interactive channels.

> Nick, is your way more "the XML" way?

The idea was to keep the implementation simple. W.r.t "tape-delay" I'm
not sold on using an anachronistic term (i.e. tape) for a new element.
Maybe broadcast-delay would be less specific in this instance?

Cheers,
Nick
