Claim 15:
16. The container of claim 15 in which the first machine-readable indicia and the second machine-readable indicia are a first digital watermark pattern and a second digital watermark pattern, wherein the first signaling protocol differs from the second signaling protocol by one or more of: (a) a reference signal used by the first signaling protocol to enable determination of geometric pose, (b) a physical size of a block of the first digital watermark pattern, (c) a number of element locations in said block of the first digital watermark pattern, (d) a waxel resolution of the first digital watermark pattern, (e) a type of error correction coding used in the first signaling protocol, (f) a redundancy rate employed in the first signaling protocol, (g) a type of CRC method used in the first signaling protocol, (h) a scrambling key used in the first signaling protocol to scramble a signature string, (i) a spreading key used in the first signaling protocol to produce a multitude of randomized chips from each bit of a scrambled signature string, (j) scatter table data that defines placement of chips in said block of the first digital watermark pattern.
