Supported image types

There was a submission about Supported Image Types [1].

I totally support the idea of a list of supported media formats and  
images are certainly on top of the list.

I disagree on the suggested type, which reads:"The property is an  
unordered set of strings". I would rather suggest a list of  
properties for every image type and subtype and use a boolean type.  
This should be managed much more easily by developers and adaptation  
softwares. I suspect that an unordered list (as suggested in the  
Measurement field) will result in a long list hardly understandable,  
I cannot imaging how sub-properties such as the loop function in an  
animated GIF will be described in such a list, mixed with compression  
factors, transparency and so on.

Everyone knows how this is managed in WURFL (exactly as I suggest),  
but I'd be curious to know how commercial products manage this, if  
you can share it.
