Then it's a good thing RFC 5897 provides guidance on that front:

   "The best way to avoid this problem is to use feature tags that can be
    matched to well-defined signaling features -- media types, required
    SIP extensions, and so on.  In particular, the golden rule is that
    the granularity of feature tags must be equivalent to the granularity
    of individual features that can be signaled in SIP."
