Section 20:
The Contact, From, and To header fields contain a URI. If the URI
contains a comma, question mark or semicolon, the URI MUST be
enclosed in angle brackets (< and >). Any URI parameters are
contained within these brackets. If the URI is not enclosed in angle
brackets, any semicolon-delimited parameters are header-parameters,
not URI parameters.
