This example as the wrong length unless you want every from wire
reader to be re-written to not look for the root label.  Given the
comment about no compression pointers this should be wire format
not text format.

	"com." has length 0x05  (0x03 0x63 0x6f 0x6d 0x00)

o  The upstream Recursive Resolver adds the CHAIN option to the DNS
      response as follows:

      *  Option-code, set to 13

      *  Option-length, set to 0x00 0x04

      *  The Closest Trust Point is set to "com.".
