You have to be carefully in exploring new options that you don't cause
issues elsewhere. I think changing duration is a case in point, as it is
not only used in hAudio, but also in hCalendar and in turn hResume.

Agreed duration is based on
http://tools.ietf.org/html/rfc2445#section-4.8.2.5, I have always had an
issue with this kind of mark-up in microformats this...
PT1H0M0S
...if you stuff it in a title its data injected into a human area!
surely this should be documented as an anti-pattern?, I am not saying
this is wrong, it happens, its just that the data above is the expected
output to a *machine*, which is surely a problem of the parser not the
author to parse this correctly.
<span class="duration">
<span class="h">1</span>:
<span class="min">3</span>:
<span class="s">42</span>
</span>
Its quite easy to extract PT1H3M42S from the data above because all the
base properties are present @duration=>PT, h=>H, min=>M, s=>S
however I can not change the way duration is currently parsed, so it
may be an idea to change @class="duration" in haudio to
class="interval" although I am unsure if this is sound thinking yet.

Having different datatypes for a property of the same name is very
problematic. Personally I would not like us to use ISO-8601 for
hCalendar duration and ISO-31-1 for duration in hAudio. Some parsers do
try to convert formats into datatypes this could become hellish if we
use the same property names for different data formats.
Last but not least you have also just walked into the internalisation
issue from the "Human and machine readable data format" debate. Not all
languages use the Arabic numerals ie 0,1,2, 3 etc
[1] http://en.wikipedia.org/wiki/Japanese_numerals
Although most people will understand Arabic numerals and you find them
mixed in with languages like Chinese, it's still an issue that need
thought.

Agreed to a certain extent but I believe that commonly Japanese Numerals
are Written in arabic ?
and I also believe that Arabic numerals are by far the most common form
of Numbering in the world?
http://en.wikipedia.org/wiki/Arabic_numerals
I believe we should keep it simple an focus around the Arabic numbering
system for now.
Thanks for your input Glenn :-)
