In general, key system [1] strings will commonly be described using lower-case
(following the reverse domain name convention). We propose that any matching
against key system should be done case sensitively to avoid having to define
interoperable case-handling rules and to simplify coding. This will usually
mean simply always specifying strings in lower case.

This will be important for the isTypeSupported method [2] and the keystem
source attribute [3].
