Although better than the binary format, I doubt that it would be useful. I can't imagine a real use case where you would want such match. Instead, what you want is a match on a particular TLV, wherever it is in the data. For start, we can support just a single TLV. I.e. when matching on TLV-A, all of these would match: TLV-A,TLV-B,TLV-C; TLV-B,TLV-A,TLV-C; TLV-B,TLV-C,TLV-A. And this one won't match: TLV-B,TLV-C,TLV-D. Jiri
