Your example is correct as far as it goes, but as I
understand it, you are not really specifying the default
catalog per se, but the default catalog *name*. Therefore,
it will then look for the nearest catalog of the name that
you have redefined as the default.

So if you redefine it to be ZCatalog1, and you have the
following structure:

/
|-/Catalog
|
|-/ZCatalog1
|
|-/folder1
|  |
|  |-/folder1/ZCatalog1
|
|-/folder2

Assuming a CatalogAware ZClass has had it's default_catalog
defined to be 'ZCatalog1', and that an instance of this
ZClass is then added in /folder2, it will index itself in
/ZCatalog1, whereas an instance that is added in /folder1
will index itself in /folder1/ZCatalog1.

This is my current understanding, I apologise if what I've
said is incorrect.
