Description

Parameter names are allowed to have spaces in them, but any parameter with a space cannot be referenced from within Expression Language. For example, we cannot use:
${#

{My Parameter}

:toUpper()} or ${ #

{'My Parameter'}

:toUpper()}

We should be able to reference the parameter using the single ticks in order to quote the parameter name.
