//     Attributes               | Attributes
//    --------------------------+----------------------------------------------------------
//     a (Array)                | A Boolean flag indicating whether the cell's formula
//                              | is an array formula. True if this cell's formula is
//                              | an array formula, false otherwise. If there is a
//                              | conflict between this attribute and the t attribute
//                              | of the f element (§18.3.1.40), the t attribute takes
//                              | precedence. The possible values for this attribute
//                              | are defined by the W3C XML Schema boolean datatype.
//                              |
//     i (Sheet Id)             | A sheet Id of a sheet the cell belongs to. If this is
//                              | omitted, it is assumed to be the same as the i value
//                              | of the previous cell.The possible values for this
//                              | attribute are defined by the W3C XML Schema int datatype.
//                              |
//     l (New Dependency Level) | A Boolean flag indicating that the cell's formula
//                              | starts a new dependency level. True if the formula
//                              | starts a new dependency level, false otherwise.
//                              | Starting a new dependency level means that all
//                              | concurrent calculations, and child calculations, shall
//                              | be completed - and the cells have new values - before
//                              | the calc chain can continue. In other words, this
//                              | dependency level might depend on levels that came before
//                              | it, and any later dependency levels might depend on
//                              | this level; but not later dependency levels can have
//                              | any calculations started until this dependency level
//                              | completes.The possible values for this attribute are
//                              | defined by the W3C XML Schema boolean datatype.
//                              |
//     r (Cell Reference)       | An A-1 style reference to a cell.The possible values
//                              | for this attribute are defined by the ST_CellRef
//                              | simple type (§18.18.7).
//                              |
//     s (Child Chain)          | A Boolean flag indicating whether the cell's formula
//                              | is on a child chain. True if this cell is part of a
//                              | child chain, false otherwise. If this is omitted, it
//                              | is assumed to be the same as the s value of the
//                              | previous cell .A child chain is a list of calculations
//                              | that occur which depend on the parent to the chain.
//                              | There shall not be cross dependencies between child
//                              | chains. Child chains are not the same as dependency
//                              | levels - a child chain and its parent are all on the
//                              | same dependency level. Child chains are series of
//                              | calculations that can be independently farmed out to
//                              | other threads or processors.The possible values for
//                              | this attribute are defined by the W3C XML Schema
//                              | boolean datatype.
//                              |
//     t (New Thread)           | A Boolean flag indicating whether the cell's formula
//                              | starts a new thread. True if the cell's formula starts
//                              | a new thread, false otherwise.The possible values for
//                              | this attribute are defined by the W3C XML Schema
//                              | boolean datatype.
