Currently, everything is very weakly worded, because the text contains many SHALLs and SHOULDs. Shouldn't we be stricter and require that any compliant consistent sampler implementation MUST follow all the rules defined here? |

@oertl According to this RFChttps://www.[ietf.org/rfc/rfc2119.txt](https://www.ietf.org/rfc/rfc2119.txt), MUST and SHALL are equivalent. I thought I had read a document that said to prefer SHALL, but now I can't find it, and I'm finding lots of other ones that prefer MUST, so yeah, I've changed it. I've tried to address most of the comments. |

…rt OTEP 235) (#31894) **Description:** Creates new sampler modes named "equalizing" and "proportional". Preserves existing functionality under the mode named "hash_seed". Fixes #31918 This is the final step in a sequence, the whole of this work was factored into 3+ PRs, including the new `pkg/sampling` and the previous step, #31946. The two new Sampler modes enable mixing OTel sampling SDKs with Collectors in a consistent way. The existing hash_seed mode is also a consistent sampling mode, which makes it possible to have a 1:1 mapping between its decisions and the OTEP 235 randomness and threshold values. Specifically, the 14-bit hash value and sampling probability are mapped into 56-bit R-value and T-value encodings, so that all sampling decisions in all modes include threshold information. This implements the semantic conventions of open-telemetry/semantic-conventions#793, namely the `sampling.randomness` and `sampling.threshold` attributes used for logs where there is no tracestate. The default sampling mode remains HashSeed. We consider a future change of default to Proportional to be desirable, because: 1. Sampling probability is the same, only the hashing algorithm changes 2. Proportional respects and preserves information about earlier sampling decisions, which HashSeed can't do, so it has greater interoperability with OTel SDKs which may also adopt OTEP 235 samplers. **Link to tracking Issue:** Draft for open-telemetry/opentelemetry-specification#3602. Previously #24811, see also open-telemetry/oteps#235 Part of #29738 **Testing:** New testing has been added. **Documentation:** ✅ --------- Co-authored-by: Juraci Paixão Kröhling <juraci.github@kroehling.de>
