Typically config space for a device is mapped out into capability specific handlers and unassigned space. The latter allows direct read/write access to config space. Sometimes we know about registers living in this void space and would like an easy way to virtualize them, similar to how BAR registers are managed. To do this, create one more pseudo (fake) PCI capability to be handled as purely virtual space. Reads and writes are serviced entirely from virtual config space.
