A spec to set default terminal applications?

[Jan Tojnar]

I would like to add that this looks like an omission in the Desktop 
Entry Specification, since the Terminal key is only described as

 > Whether the program runs in a terminal window. [1]

but it is not clear what does that mean. The specification should 
clarify, link to another specification, or, in the worst case, 
explicitly say that it is implementation dependent.
