Ok, the key is *not* to define the method inside the class.
To wrap it up in case someone searches the list:

1) define a python script somewhere in the acquisition path where the 
catalog  will pick it up. Since mine is a CMF Product I used the skin 
directory. Call it, e.g., index_yourattribute

2) the content of the script is

attr=getattr(context.aq_explicit,'yourattributename')
if callable(attr): attr=attr()
return attr

3) define an index and/or metadata called like the python script 
(index_yourattribute)

4) enjoy :-)
