Things are not that bad - in practice, there is little point in 
checking for anything but a handful of standard formats. In 
particular, you are very unlikely to find any application that 
supplies data in more than one non-standard (i.e., "native") format, 
so there is no need to check for any unknown type. The usual situation 
is that either the data is in a standard format already (e.g., Text), 
or it is native (e.g., EasiWriter), plus one or more alternative 
standard formats. So, if you request the native data and then Text, 
Sprite, Draw, HTML and CSV you have covered pretty much all of them.
