 ### Term payloads
 Some terms are indexed with a TUI in their payloads, if they take part in a relation.
 Terms may also have a certainty value attached, expressed as a byte (with a ranging certainty value from probably incorrect to probably correct (0-255)). For example:
+
     pos:NN$<b>128<s>1
     pos:NN$<b>129<b>34
     pos:NN$<b>130<s>1<b>34
