The <span> element contains media that make up all or parts of the <feed>. A <span> element describes its duration and the path to the physical media files. A <feed> made up of multiple <span> elements means that multiple media files/sequences make up that one <feed>. The order in which each <span> element is listed is the order in which they are read to rebuild the sequence.
All media referenced in a <span> must have homogeneous properties (same codec, compression, format, length, rate...). To mix types of media in a <clip>, use different <track> elements.
A <span> with a <duration> but no <path> is a gap.
