- Added validation for empty values in Assert-ConfigurationDataParameter. - Introduced Assert-ConfigurationDataSecretReference for secret reference validation. - Implemented Test-ConfigurationDataExpressionParentheses to validate expression syntax. - Added Test-ConfigurationDataMissingReferenceError to check for missing parameter or variable definitions. - Updated Invoke-ConfigurationDataExpression to handle new validation logic. - Revised Readme.md to reflect changes in secret reference handling.
