I'd like to call this method out of the DTML file 'index_html' in the =

'attribute' of the path '/sap_root/documentation/attribute'. How can I =
do
that?
I already tried:
***index_html***
<html>
<dtml-var "sap_root.leaves.merkmale.merkmale_index()">
</html>
This fails because you break the DTML namespace chain.
Use:
<dtml-with "sap_root.leaves.merkmale">
     <dtml-var "merkmale_index">
   </dtml-with>

or:

   <dtml-var "sap_root.leaves.merkmale.merkmale_index(_.None,_)">
...
and
<html>
<dtml-var sap_root.leaves.merkmale.merkmale_index>
</html>
This fails because the first attribute of most DTML tags
is interpreted as an (atomic!) object name if it is not
enclosed in "...".
You code looks for an object with name "sap_root.leaves.merkmale.merkmale_index".
The '.' are not interpreted as the attribute access operator but
are passive parts of the name.
