cbrn:compressionCode

An algorithm, if any, by which the channel data have been compressed.  If this attribute is omitted, the data have not been compressed.  The kinds of data compression are as follows:  - None: the data are not compressed.  The number of values in the ChannelData element is equal to the number of channels of data represented by the element. - CountedZeroes: the data have been compressed by the removal of repeated zero values. When a "0" value appears in the ChannelData contents, the next value is the number of consecutive zero-value channels beginning with the first zero-value in the sequence. For example, the following 18 channels of uncompressed data: 22 5 0 2 1 0 0 3 4 0 0 0 0 0 0 0 0 1 would be represented in compressed form by 22 5 0 1 2 1 0 2 3 4 0 8 1 The italicized values in the list show cases where one, two, and eight zeroes have been compressed.
