The value for policy.authority-uri contains characters that are not allowed in a simple token, so it must be in quotes to be a quoted-string (https://www.rfc-editor.org/rfc/rfc2045#section-5.1 contains the definition for value which is used by ARH here).

From the referenced RFC

tspecials := "(" / ")" / "<" / ">" / "@" / "," / ";" / ":" / "\" / <"> "/" / "[" / "]" / "?" / "=" ; Must be in quoted-string, ; to use within parameter values
