thanks for the answer, this was of course a FAQ ;-)

I personally never liked this illegal names, Would be nice to have them
as
sequence_item,...


Today seems my problem day: :-) After getting answers for all this
problems
of course I have another one 

I want to delete the image-object with id="banner" in the "Wo"-Folder 
("Wo" means "Where" in German)
e.g.
<dtml-call "manage_delObjects(ids=['banner'])">  .


<dtml-if "_.hasattr(Wo, 'banner')">
does not work as a condition, because Aquisition takes place. I have
an object banner at the root-directory!

Question: What is the correct was of programming the following:

Delete an image with id="banner" in a certain Folder named "Wo",
but only if there is really one contained there (Aquisition is not
allowed).
I really tried all kind af namespace-manipulations here,
also the _.None.. stuff, but I can't find a solution.
