#: This table defines the "Error Correction Code Words and Block Information."
#: The table lists the number of error correction words that are required
#: to be generated for each version and error correction level. The table
#: is accessed by first using the version number as a key and then the
#: error level. The array values correspond to these columns from the source
#: table:
