<xsd:documentation>The actual data corresponding to the curves defined in
the LOGCURVEINFO element. A comma delimited list of data values with one
value for each curve on the log (e.g., "xxx,yyy, zzz"). For array curves,
the value of the array curve 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 curve
mnemonics represent the column headings.
The order of the nodes for each block should match the order implied
