I would just tag a sentence to the end of the parag you suggested:

    If the 3GPP network supports both IPv4 and IPv6 PDP contexts, the UE may
    activate the appropriate PDP context depending on the type of
    application it has started; it may also make sense to open both PDP
    contexts in advance, before they are used, because the activation of
    a context may take a relatively long time. If both PDP Contexts are
    not opened in advance then it may be necessary for an application
    to trigger the creation of a new PDP Context when it determines
    that a communication to an IPv6 peer is required and an IPv6 PDP
    Context is not available.
