That's correct, although the example Windows LaunchApp record 
unfortunately also represents a violation of the TNF=3 type string 
construction rules - it should in fact be an Absolute URI.

Beyont that, shouldn't the Blob message type not actually apply to *any* 
NDEF record type that is not covered by DOMString | URL | JSON ? I would 
else wonder how other NFC Forum Well-Known Types or NFC Forum External 
Types (TNF=4) could be accessed.
