  19. // --------------------------+----------------------------------------------------------
  20. // a (Array) | A Boolean flag indicating whether the cell's formula
  21. // | is an array formula. True if this cell's formula is
  22. // | an array formula, false otherwise. If there is a
  23. // | conflict between this attribute and the t attribute
  24. // | of the f element (§18.3.1.40), the t attribute takes
  25. // | precedence. The possible values for this attribute
  26. // | are defined by the W3C XML Schema boolean datatype.
  27. // |
  28. // i (Sheet Id) | A sheet Id of a sheet the cell belongs to. If this is
  29. // | omitted, it is assumed to be the same as the i value
  30. // | of the previous cell.The possible values for this
  31. // | attribute are defined by the W3C XML Schema int datatype.
  32. // |
  33. // l (New Dependency Level) | A Boolean flag indicating that the cell's formula
  34. // | starts a new dependency level. True if the formula
  35. // | starts a new dependency level, false otherwise.
  36. // | Starting a new dependency level means that all
  37. // | concurrent calculations, and child calculations, shall
  38. // | be completed - and the cells have new values - before
  39. // | the calc chain can continue. In other words, this
  40. // | dependency level might depend on levels that came before
  41. // | it, and any later dependency levels might depend on
  42. // | this level; but not later dependency levels can have
  43. // | any calculations started until this dependency level
  44. // | completes.The possible values for this attribute are
  45. // | defined by the W3C XML Schema boolean datatype.
  46. // |
  47. // r (Cell Reference) | An A-1 style reference to a cell.The possible values
  48. // | for this attribute are defined by the ST_CellRef
  49. // | simple type (§18.18.7).
  50. // |
  51. // s (Child Chain) | A Boolean flag indicating whether the cell's formula
  52. // | is on a child chain. True if this cell is part of a
  53. // | child chain, false otherwise. If this is omitted, it
  54. // | is assumed to be the same as the s value of the
  55. // | previous cell .A child chain is a list of calculations
  56. // | that occur which depend on the parent to the chain.
  57. // | There shall not be cross dependencies between child
  58. // | chains. Child chains are not the same as dependency
  59. // | levels - a child chain and its parent are all on the
  60. // | same dependency level. Child chains are series of
  61. // | calculations that can be independently farmed out to
  62. // | other threads or processors.The possible values for
  63. // | this attribute are defined by the W3C XML Schema
  64. // | boolean datatype.
  65. // |
  66. // t (New Thread) | A Boolean flag indicating whether the cell's formula
  67. // | starts a new thread. True if the cell's formula starts
  68. // | a new thread, false otherwise.The possible values for
  69. // | this attribute are defined by the W3C XML Schema
  70. // | boolean datatype.
