[Mediawiki-l] mediawiki admonitions

[Maurizio Vitale]

Good day,
	I've been trying to locate an extension for displaying docbook-like  
admonitions (things like note, tip, warning, error). I've seen it  
used in a few mediawiki-based sites and cannot imagine that everybody  
has written his own implementation. But I haven't been able to locate  
this among the mediawiki extensions.
Pointers anyone?
Thanks a lot,

		Maurizio
