## General comments
## Merge activities without targets gives little additional information beyond what the deprecated activity provides.
## Understanding when/what merge/split has happened requires a link between the old heading and new heading in source data.
## MARC practice is to capture this in a semi-machine-actionable way for Names in the 667 $i of the new heading "Formally..."
## For new subjects in the 010 $z (old id) and deprecated subject 682 $i (new id).
## A variant label for the previously undifferentiated heading is added to the new authority if the undifferentiated heading is deleted (1XX and 4XXs can't match).
## In LC implementation, MADSRDF seemingly points from old headings to new headings using madsrdf:useInstead for LCSH, but not Names.




## Scenario: All of X replaced by Z (full merge/replacement), X is deprecated
## Does Merge imply two or more things becoming one, or can one thing be merged into another?

## Scenario: X isn't replaced by Y, instead preferred heading for X is simply updated. In some/most cases rather than deprecating the old heading the 1XX is updated instead; this could just be a change.

## Scenario: Parts X are now considered Z (Partial split), and all of Y are Z (replaced), Y is deprecated
## Should split and merge activities signal complete splits/merges? Partial split/merges signaled as changes? Or Deprecation signals completeness?
