It is Cocoon slang: http://archives.real-time.com/pipermail/cocoon-devel/2000-June/000110.html

Here, you can find people asking for more and more features they are used to:

• WikiAttachments, which could have a good use, can also be used lazily to post word documents with discussion material. For this, I would prefer writing a tool to convert Word markup to WikiMarkup :-)
• HTML inside WikiMarkup is bad. It will bring back most of the problems we are running from

Just examples, just my opinion. --SantiagoGala
