This answers the question, but how knows PmWiki about this?

For example I use the property A with

	$page['A']= 'foo';
	WritePage(...,$page);

in my own script (never with the property markup) and a property B on  
the page with

	(:property B=value:)

Now I delete the markup

	(:property B=value:)

from the page. So property B will be deleted when I save the page  
again. But how does PmWiki knows, that property A wasn't on the page  
before (I think a diff for every property is really slow)? This was  
my only concern. But if it works, I'm fine.

Uh, I'm discovering $PageAttributes right now. That's a really nice  
feature. :)
