net.sf.saxon.sxpath.IndependentContext.declareVariable()
Declare a variable. A variable must be declared before an expression referring to it is compiled. The initial value of the variable will be the empty sequence @param qname The name of the variable @return an XPathVariable object representing information about the variable that has beendeclared.

            // self-declaring variables modify the static context. The XPathCompiler must not change state
            // as the result of compiling an expression, so we need to copy the static context.
            ic = env.copy();
            for (Iterator iter = env.iterateExternalVariables(); iter.hasNext();) {
                XPathVariable var = (XPathVariable)iter.next();
                XPathVariable var2 = ic.declareVariable(var.getVariableQName());
                var2.setRequiredType(var.getRequiredType());
            }
        }
        try {
            XPathEvaluator eval = new XPathEvaluator(processor.getUnderlyingConfiguration());
