I'm having a problem with some old xalan-1 code. A value is conditionally
assigned to the DefaultFilter parameter. $OSHProfile/filter/default does
not exist in the stylesheet parameter $OSHProfile. The not($DefaultFilter)
test always evaluates to false. This is because an RTF is never really
null, as I understand it.
It isn't clear to me how to rewrite this logic so it will work in xalan
2.5.0. I thought about using a boolean; but I have to be able to test
$OSHProfile/filter/default for a null value to assign the boolean variable.
Is there a way to reliably test an RTF for null?
Is there some other workaround that I am not seeing?
Thanks...
