JavaScript EXPRESSION Parameters

EXPRESSION parameters are variables within a function that result in a URL when they are evaluated. The syntax for EXPRESSION parameters is

<Function type = "EXPRESSION" name = "function" [paramPatterns="y,y,"] />

where function is the name of the function to be evaluated and y indicates the position of the parameter(s) that need to be rewritten. Parameter positions are delimited by commas. For example, in the syntax line the first and second parameters need to be rewritten, but the third parameter should not be rewritten.
