i've wondered about forms such as "file://C:/Files/Schemas/test.xsd", which specifies a "host" "C:". is there any concensus on how such designators whould be
interpreted in os/language contexts which include the notion of logical hosts and or devices?

i'm also curious what one should expect something like "file:Schemas/test.xsd" to mean and if so, according to which rules?
