@rId is the revision Id, and indicates the order in which the particular revision should be applied.

@sId indicates the sheet to which this revision applies.

<rcc> means "revision cell change"

<nc> means new cell, and is of type CT_Cell (see §3.2 for more information on the cell definition). Note that instead of using a shared string table, strings are expressed inline for these cells.

<rrc> means "revision row/column". Note that <rrc> can have an associated action, like @insertRow (or @deleteRow), which would cause a row to be inserted (or deleted) at that step in the series of revisions.
