-- Use one of the following lenses to modify other fields as desired:
--
-- * 'uarpRoleName' - The name of the role to update with the new policy. This parameter allows (per its <http://wikipedia.org/wiki/regex regex pattern> ) a string of characters consisting of upper and lowercase alphanumeric characters with no spaces. You can also include any of the following characters: _+=,.@-
--
-- * 'uarpPolicyDocument' - The policy that grants an entity permission to assume the role. The <http://wikipedia.org/wiki/regex regex pattern> used to validate this parameter is a string of characters consisting of the following:     * Any printable ASCII character ranging from the space character (\u0020) through the end of the ASCII character range     * The printable characters in the Basic Latin and Latin-1 Supplement character set (through \u00FF)     * The special characters tab (\u0009), line feed (\u000A), and carriage return (\u000D)
