Section 23.3 says:

Content-Disposition: attachment; filename=smime.p7m
           handling=required

It should say:

Content-Disposition: attachment; filename=smime.p7m;
           handling=required

Notes:

The example for Content-Disposition header is incorrectly formatted according to the BNF.
It is missing a semicolon between each disp-param.
(Relevant section of BNF posted below)

Content-Disposition = "Content-Disposition" HCOLON
disp-type *( SEMI disp-param )
disp-type = "render" / "session" / "icon" / "alert"
/ disp-extension-token
disp-param = handling-param / generic-param
handling-param = "handling" EQUAL
( "optional" / "required"
/ other-handling )
other-handling = token
disp-extension-token = token

This also occurs in 23.4.3
