NO.1 Calculating sub-totals from an XML document using XSL transformation requires special
considerations. Which of the following options is the best solution to solve this problem?
A. Create a fragment variable containing the values to total, and then use the node-set() XSLT extension
and the XPath "sum()" function to calculate the value.
B. Create a special XSLT variable that contains the results of an XPath query that performs a "sum()" of
the values to be totaled.
C. Use XSLT recursion to define a variable value that calculates the "value-of" the elements to be
sub-totaled.
D. Use XSLTC to precompile a custom Java translet that will extract the values to be totaled and returns
the sum of those values. This return value is then used in an XSL variable for output.
