Sequenced Across is an abstract Concept Class used for organizational purposes. It cannot be instantiated in the model. It represents all sequenced contexts.

Summary

Sequenced Across Contexts look for facts (and anchors) that are separated by specific gaps, called skips. How many skips can exist between the anchors and / or facts can be very precisely controlled at each point in the sequence (unlike near ordered contexts, where the gap can only be distributed anywhere in the sequence).

The skips count in the same punctuation type as the rest of the sequence. That is, if the sequence type is sentences, then specifying a skip of 5 on such a sequence will result in a skip of up to or at most 5 sentences being allowed between the preceding and succeeding elements.

Sequenced Across Contexts Properties

The following table is common to all of the Sequenced Across Contexts. They only differ in the contexts they look in and the different grammatical units that are looked for.
