Adding indexes to custom catalog

I'm creating several catalogs for different types of objects, hoping to speed things up and reduce conflicts. I've been working with this document:

http://collective-docs.readthedocs.org/en/latest/searching_and_indexing/catalog.html#minimal-code-for-creating-a-new-catalog

The site builds without errors, the catalog is created, but the indexes and metadata columns don't get added to the catalog.

I've tried adding a new block to catalog.xml, and that fails with the following error:

ExpatError: catalog.xml: junk after document element: line 158, column 0

Which is the line that my new block begins - I am guessing that catalog.xml is for portal_catalog and no other.

I've found an obvious-sounding function called ZCatalog.py/addIndex()...

But my question is - what does 'best practice' look like? What I'd really like is to find a living example of a project that adds multiple catalogs and indexes on installation.

Documentation links would also be first prize.

Thanks for your time so far. and in advance, too.

I've usually added install code to do this for me--I don't think the catalog.xml file handles additional catalogs.

cat = getToolByName(context, 'catalog_name')
cat.addIndex(name, 'FieldIndex') # or whatever index you want it to be.
# for metadata
cat.addColumn(name)

Just put something like that in an import step method.
