are you sure that is the expression that you want?
There is never any need to test if the string length of a text node is >
0 as that is a constraint on the node type (in XSLT1). so the only
effect of using the string-length function is to silently discard all
but the first text node,

test="string-length(//ACCOUNT-NO/text()) > 0"
is the same as
test="(//ACCOUNT-NO/text())[1]"
also it is a bit suspicious (and certainly inefficient) to start this
test with // as it means that it always searches the entire document and
tests the first ACCOUNT-NO that it finds, it does not depend on teh
current ACCOUBT-LIST element. So within a given document this is always
true or always fale so it could be a global variable, ther eis no need
to work it out again each time you execure a template.
