thanks for the pointer.
First, as a clarification: In the process of the integration of GoodRelations into schema.org, we decided to keep the pre-defined values of enumerations (i.e. the "instances") in the GoodRelations name space. So only the type (roughly the "class") of all allowed values is defined in the schema.org namespace.

This keeps the amount of elements in the schema.org namespace small and allows for the simple definition of additional, external values.

This having said: I will be happy to define additional instances of 

>> http://schema.org/BusinessFunction

in GoodRelations in the next service update if needed; just let me know.

Note that GoodRelations has a subtype of http://schema.org/BusinessFunction, i.e.


which has not been imported to schema.org for legal reasons (search engines have a problem with a vocabulary element that site-owners may want to use to articulate constraints on the usage of their site content beyond a binary crawl allowed / disallowed statement, as supported by robots.txt).
