Thanks for contributing - unfortunately the style doesn't validate:
http://www.zotero.org/support/dev/citation_styles#validation
Here's the output of the validator, if you have specific questions let me know.
Partly it seems like you're mixing csl 1.0 and csl 0.8.1 (this is a 0.8.1. style, but e.g. using the <et-al node in the name is a 1.0 feature).

cool, thanks, that's indeed handy.

Errors are never acceptable :).

The problems with your validation link are:

- if you use "Address" instead of "Text Field" to provide the style, you should check "Be lax about HTTP Content-Type"
- the "http://www.zotero.org/styles/chicago-note-bibliography" style is a CSL 0.8.1 style (like most other styles in the repository), so you should validate against the CSL 0.8.1 schema (http://bitbucket.org/bdarcus/csl-schema/raw/83f9cf9b53bd/csl.rnc)
