Hi, Martin:B B B B B B B  I understand what the error means.

B B B B If I run that module in Oxygen, I get:

<?xml version="1.0"encoding="UTF-8"?>
<SVM xmlns="schema://fc.fasset/svm"><!-- June 23rd, 202122:18:41 -->
B B  <Negative><!--Negativetrained Options classification::Better training
data issuggested--></Negative>

</SVM>
B B B B  => blank result

B B B  My XSLT + cts module groups the labelled classification into
NegativeB (all @val is negative in one serial/classification) and Positive
(one, only one, positive @val in one serial/classification).B  That module is
merely one-liner work.B B B B 

B B B  Can you correct my XSLT module and get the desired groups, in this
case, the Negative and the Positive?B

I think the error message is telling you that that the second argument to the
"contains" call, i.e. $classVal is a sequence of more than one item.
