DTV_ — Between

The Date Time Vocabulary provides verb concepts that relate the time order of any two time intervals (e.g. 'time interval1 is before time interval2'), any two situation models ('situation model1 precedes situation model2'), and any two occurrences ('occurrence1 precedes occurrence2'). Another common ordering relationship is among three time intervals, situation models, or occurrences, as in 'time interval1 is between time interval2 and time interval3', 'situation model1 is between situation model2 and situation model3', and 'occurrence1 is between occurrence2 and occurrence3'. These ternary verb concepts should be added to the Date Time Vocabulary.

Add the suggested verb concepts to the vocabulary. Use "and" in the primary form of the verb concepts (even though it is also a keyword for conjunction), and provide an alternate synonymous form that does not use 'and'.
