Description: 
ISSUE: Why is there an offset in the Streamable seekRead / seekWrite?
DISCUSSION: This is fine (and useful) for implementations where such an offset can be provided. Where implementations cannot provide an offsetable read/write, an  appropriate fault should be returned.
SOLUTION: Check consistency with listed faults and determine if fault is required

Consistency seems okay.

"Seek Not Permitted Failure	This failure indicates that a seek operation was attempted on a stream that doesn’t support seeking.  To avoid this failure, clients that wish to use seekRead and seekWrite on a resource that doesn’t support seeking should send in seek values indicating an offset of 0 bytes, and with the seekOrigin set to the current position value.  No specific information is required of the Profile Rendering."
