Hi Torsten, I don't think this is about plain text vs à la XML (because XML and friends are plain text too) but about whether we should allow a new type of block to keep non-human-readable stuff out of the way.
One thing I don't get is how these blocks would be more hidden than normal blocks or drawers. Another thing I'm not sure about is what kind of technical stuff you have in mind. I see what you mean for UUID, but note that this is not a problem of the :ID: property itself (which can hold a human readable value), but of the value of this property when using UUIDs. Speculating about Org possibilities is one of the fun here, so I would not mind reading a more precise example. But in general, as one can more or less guess, I'm more of a less person. :) -- Bastien
