I think this is fine, but the MAY could be interpreted in isolation as
implying that the document contains some more general prohibition on
the use of all of jCard's functionality, which might lead to
confusion.  It's hardly a big problem, but another suggestion:

    The "lang" attribute as defined in this section may appear
    anywhere in an object class or data structure, except for in jCard
    objects.  jCard supports similar functionality by way of the
    LANGUAGE property parameter: see Section 5.1 of [RFC6350].

Simply striking the second sentence is another option, too (so that
the only change from RFC 7483 is the addition of "as defined in this
section").  But in any event, I think your suggested text is fine.
