<xsd:documentation>The data values for the record.
A comma delimited list of data values with one
value for each channel in the group (e.g., "xxx,yyy, zzz"). For array channels,
the value of the array channel will be a space delimited list of values that
are contained within the commas that delimit the value for that curve
(e.g., "xxx,aa bb cc,zzz").
This essentially represents one row of a table where the channel
mnemonics represent the column headings. </xsd:documentation>
