Top-level BNode in KQL

[gmcfall]

I want to be able to specify a BNode at the top-level of a KQL formula.

For instance, I want the ability to use an expression like this in a formula:

@term contactType <http://schema.org/contactPoint>
@term Sales <http://example.com/ns/Sales>
@term email <http://schema.org/email>
@term email_address <http://example.com/ns/email_address>

[
   contactType Sales;
   email $.email_address
]
