Are these URNs always uppercase? Does case matter here? Would some or
all of the following be illegal?

	urn:CLEI:D4CE18B7AA
	urn:clei:D4CE18B7AA
	urn:clei:d4ce18b7aa
	urn:CLEI:D4CE18B7AA
	URN:CLEI:d4ce18b7aa
	URN:clei:d4ce18b7aa
	URN:clei:D4CE18B7AA

According to RFC 2141, the leading "urn:" sequence is case-insensitive.
What about the rest?
