Hi,
Progress functions are not supported in html5.
Right, the internal <progress> animations are not supported in the html5 and there are also currently no plans to support them there.
But therefore by using the 'progress.progress' value and some xml code and graphics, it would be possible to show/draw any kind of custom loading animation - that means this way this would be much more customizable and it works automatically the same for flash and html5.
E.g. see this example - it shows 3 different loading animations:

The example is also included in the viewer download package.
Best regards,
Klaus
