&templateSet
Values: [ string ]
Default: defaultString
The set of templates you’d like to use. (Templates are defined below.) It will default to defaultString which replicates the output of previous versions.
In an effort to keep the MODx chunks manager from getting mired down in lots of templates, Breadcrumbs templates are included here. Two sets are provided prefixed with defaultString, and defaultList. You can create as many more as you like, each set with it’s own prefix...

Does it mean that I have to hack the code of Breadcrumbs snippet to add a new $templateSet array element?
