It sounds like you are exactly aware of the problem then. People try to 
do something they want to do, and they all do it in different ways. A 
consumer is unable to know, reliably, what to do with this data, since 
the problem you mention is completely undocumented without a "polyglot 
specification".

Is your advice "don't do this"? If so, what would you have them do 
instead? If your advice is "do it this way", where is the specification 
that shows this way?
