Can SegmentTemplate @duration be a non-integer?

[joeyparrish]

In this sample:
https://dash.akamaized.net/akamai/bbb_30fps/bbb_with_multiple_tiled_thumbnails.mpd

We found this snippet:

  <AdaptationSet id="3" mimeType="image/jpeg" contentType="image">
    <SegmentTemplate media="$RepresentationID$/tile_$Number$.jpg"
        duration="634.566" startNumber="1"/>

Is this sample of out conformance to the spec for having a non-integer duration attribute (634.566)? Should the content be fixed to use something like duration="634566" timescale="1000" instead? Or should players always assume that duration could be a non-integer?

Thanks!

The DASH specification defines duration to be of type xs:unsignedInt, so I think the example violates the spec.

The answer from @ojw28 is correct. Thanks

FYI, this is easily checked with the XML schema which is authoritative over the text in the standard:

The latest code release matches the forthcoming 5th Ed. But it includes a good amount of better datatyping in general.
