This is the way to tell Wicket to not add a value for the attribute. Okay. I've never seen this before. That's why I was asking.

Yes, but I prefer the "dynamic" way. A Component/Page provides some kind of "microdata" and implements an interface. The AttributeAppender takes the information and writes the appropriate attribute at the tag. Martin Grigorov-4 wrote >> seen this before)? Or is this marker value for internal use only?
