A possible way to solve one of Jag's use cases

// alt 1
ref-value-triple1 = {
  environment: X
  ref-claims: [
    [ mkey = kernel, mval = { digest=0xfe... } ]
    [ mkey = wkld, mval = { digest=0xbb... } ]
  ]
}

// alt 2
ref-value-triple2 = {
  environment: X
  ref-claims: [
    [ mkey = kernel, mval = { digest=0xff... } ]
    [ mkey = wkld, mval = { digest=0xaa... } ]
  ]
}
