Guess I wasn't clear enough this time either... :-)

So how about if you look at this example and tell me if it'll fly...

Thanks, I added this here (although it's probably too complicated as a
"simple" example):

I guess what's really needed is a good description of Markup() together 
with plenty of examples of how to use it. So I searched pmwiki.org and 
found the description here:

	http://www.pmwiki.org/wiki/PmWiki/CustomMarkup

In order to make it easier to find the page above, I added small entry 
here:

	http://www.pmwiki.org/wiki/PmWiki/Functions#Markup

that primarily refers to PmWiki.CustomMarkup.
