Description

Need to update `nfel` to support referencing parameters within expression language. A parameter reference should be allowed outside of an expression, as a subject to an expression, or as a parameter to a function in an expression.

${#{abc}:toUpper()}
#{abc}${attr:toUpper()}
${attr:contains(#{abc})}
