ZDoom Map Formats?

[Doom_user]

What's the difference between the Doom in Doom format and the Doom in Hexen format, is there anything that can be done in one and not the other?

There is a lot more that can be done in the Hexen map format which you cannot do in the Doom map format. But not the other way around. However, not all sourceports support the Hexen map format.

Is there any documentation on editing for the ZDoom (Doom in Doom) format? The Zdoom wiki only seems to cover the ZDoom (Doom in Hexen) format.
