Details
Description
In MXF all data shall be KLV ("key-length-value") encoded without gaps.

The only exception is the optional "run-in" which is only allowed in specialized operational patterns (forbidden e.g. in OP1a), which can be any data in the first 65536 bytes of the MXF file.
Definition
Used in Checks, the system shall check if the KLV structure is valid. Optionally, the system may report the position and byte lengths of invalid KLV data.

Used in Reports, the system shall report the position and byte lengths of invalid KLV data.
