[Zope] ZCatalogAware: changing catalog name

[Karsten Kraus]

Hi there,

I used the Chapter about "Automatic Cataloging" as base for my
own catalog-aware Product.
It works as expected, if the ZCatalog has the Id 'Catalog', but doesn't work
if I give it an other id (e.q. TestCatalog).
Where do can I change the id used for the ZCatalog in my Product/ZClass?

TIA
Karsten
