* As a JSON or YAML value by placing values in the form `${PARAMETER_NAME}` in place of any field in the template.
* As a JSON or YAML value by placing values in the form `${{PARAMETER_NAME}}` in place of any field in the template.
When using the `${PARAMETER_NAME}` syntax, multiple parameter references can be combined in a single field and the reference can be embedded within fixed data, such as `"http://${PARAMETER_1}${PARAMETER_2}"`. Both parameter values are substituted and the resulting value is a quoted string.
When using the `${PARAMETER_NAME}` syntax only a single parameter reference is allowed and leading and trailing characters are not permitted. The resulting value is unquoted unless, after substitution is performed, the result is not a valid JSON object. If the result is not a valid JSON value, the resulting value is quoted and treated as a standard string.
