Yes, I get that.

As I said, the real-world example is the Banner Product:

root
 +--- BroDar (Folder)
 |     +--- BotaoBroDar (BannerAd)
 +--- lalo (Folder)
       +--- aqtest (DTML Method)

Documents under ``BroDar'' can include the button by using
<dtml-var BotaoBroDar>. Works.

But if something under ``lalo'' tries to include it
(<dtml-var "BroDar.BotaoBroDar">), it will generate something
like: <a href="BotaoBroDar/hit"><img src="BotaoBroDar"></a>
which of couse won't work.

I worked around this by copying the button to my folder.

In the BannerFolder ZClass, I work around this by doing the
Python equivalent of sed'ing the BannerAd output to convert it
to something like
<a href="banner/BotaoBroDar/hit"><img src="banner/BotaoBroDar"></a>
(where ``banner'' is the name of the BannerFolder).

But I wonder if there isn't a better way.
