Ward called this "hiding the gibberish", new term for me as a non native speaker. To explain this tag to someone you could say "This is the gibberish tag" - If people see this they can safely skipp it, but instead of seeing that huge "gibberish" code that they don't understand, they just see this.
I like the word "gibberish" (or "native") far more than I like the world "Placeholder". The word "placeholder" implies that the markup is not in mixed mode, but rather in creole mode.
I think we might want to invent a better name. I suggest "WikiSpeck" - as in a "smudge". It's also a bad non-native English speaker pun on the word "WikiSpeak"...
Can you give an example of placeholder usage?

The difference between placeholders and transclusions is not very clear, at least for me.
However, there should be a way (a suggested way) to include metadata about the document (author, date, location, dublin-core-like info). Could placeholder be used for this kind of extensions?
