+
+The @code{footnote-number}, if present, specifies a footnote that the
+Value references. The footnote's marker is shown appended to the main
+text of the Value, as a superscript.
+
+The @code{subscript}, if present, specifies a string to append to the
+main text of the Value, as a subscript. The subscript text is a brief
+indicator, e.g.@: @samp{a} or @samp{a,b}, with its meaning indicated
+by the table caption. In this usage, subscripts are similar to
+footnotes; one apparent difference is that a Value can only reference
+one footnote but a subscript can list more than one letter.
+
+The Format, if present, is a format string for substitutions using the
+syntax explained previously. It appears to be an English-language
+version of the localized format string in the Value in which the
+Format is nested.
+
+The Style, if present, changes the style for this individual Value.

+@node SPV Legacy Detail Member Binary Format
+@section Legacy Detail Member Binary Format
+
+Whereas the light binary format represents everything about a given
+pivot table, the legacy binary format conceptually consists of a
+number of named sources, each of which consists of a number of named
+series, each of which is a 1-dimensional array of numbers or strings
+or a mix. Thus, the legacy binary member format is quite simple.
+
+This section uses the same context-free grammar notation as in the
+previous section, with the following additions:
+
+@table @asis
+@item vAF(@var{x})
+In a version 0xaf legacy member, @var{x}; in other versions, nothing.
+(The legacy member header indicates the version; see below.)
+
+@item vB0(@var{x})
+In a version 0xb0 legacy member, @var{x}; in other versions, nothing.
+@end table
+
+A legacy detail member @file{.bin} has the following overall format:
+
+@cartouche
+@format
+LegacyBinary @result{}
+ 00 byte[@t{version}] int16[@t{n-sources}] int[@t{member-size}]
+ Metadata*[@t{n-sources}] Data*[@t{n-sources}]
+@end format
+@end cartouche
+
+@code{version} is a version number that affects the interpretation of
+some of the other data in the member. Versions 0xaf and 0xb0 are
+known. We will refer to ``version 0xaf'' and ``version 0xb0'' members
+later on.
+
+A legacy member consists of @code{n-sources} data sources, each of
+which has Metadata and Data.
+
+@code{member-size} is the size of the legacy binary member, in bytes.
+
+The following sections go into more detail.

+Metadata @result{}
+ int[@t{per-series}] int[@t{n-series}] int[@t{offset}]
+ vAF(byte*32[@t{source-name}])
+ vB0(byte*64[@t{source-name}] int[@t{x}])
+@end format
+@end cartouche
+
+A data source consists of @code{n-series} series of data, with
+@code{per-series} data values per series.
+
+@code{source-name} is a 32- or 64-byte string padded on the right with
+zero bytes. The names that appear in the corpus are very generic,
+usually @code{tableData} or @code{source0}.
+
+A given Metadata's @code{offset} is the offset, in bytes, from the
+beginning of the member to the start of the corresponding Data. This
+allows programs to skip to the beginning of the data for a particular
+source; it is also important to determine whether a source includes
+any string data (@pxref{SPV Legacy Member Data}).
+
+The meaning of @code{x} in version 0xb0 is unknown.
+
+@node SPV Legacy Member Data

+Data @result{} NumericData StringData?
+NumericData @result{} NumericSeries*[@t{n-series}]
+NumericSeries @result{} byte*288[@t{series-name}] double*[@t{per-series}]
+@end format
+@end cartouche
+
+Data follow the Metadata in the legacy binary format, with sources in
+the same order. Each NumericSeries begins with a @code{series-name}
+that generally indicates its role in the pivot table, e.g.@: ``cell'',
+``cellFormat'', ``dimension0categories'', ``dimension0group0'',
+followed by the numeric data, one double per element in the series. A
+double with the maximum negative double @code{-DBL_MAX} represents the
+system-missing value SYSMIS.
+
+@cartouche
+@format
+StringData @result{} i1 string[@t{source-name}] Pairs Labels
+
+Pairs @result{} int[@t{n-string-series}] PairSeries*[@t{n-string-series}]
+PairSeries @result{} string[@t{pair-series-name}] int[@t{n-pairs}] Pair*[@t{n-pairs}]
+Pair @result{} int[@t{i}] int[@t{j}]
+
+Labels @result{} int[@t{n-labels}] Label*[@t{n-labels}]
+Label @result{} int[@t{frequency}] int[@t{s}]
+@end format
+@end cartouche
+
+A source may include a mix of numeric and string data values. When a
+source includes any string data, the data values that are strings are
+set to SYSMIS in the NumericSeries, and StringData follows the
+NumericData. A source that contains no string data omits the
+StringData. To reliably determine whether a source includes
+StringData, the reader should check whether the offset following the
+NumericData is the offset of the next series, as indicated by its
+Metadata (or the end of the member, in the case of the last source).
+
+StringData repeats the name of the source (from Metadata).
+
+The string data overlays the numeric data. @code{n-string-series} is
+the number of series within the source that include string data. More
+precisely, it is the 1-based index of the last series in the source
+that includes any string data; thus, it would be 4 if there are 5
+series and only the fourth one includes string data.
+
+Each PairSeries consists a sequence of 0 or more Pair nonterminals,
+each of which maps from a 0-based index within series @code{i} to a
+0-based label index @code{j}, e.g.@: pair @code{i} = 2, @code{j} = 3,
+means that the third data value (with value SYSMIS) is to be replaced
+by the string of the fourth Label.
+
+The labels themselves follow the pairs. The valuable part of each
+label is the string @code{s}. Each label also includes a
+@code{frequency} that reports the number of pairs that reference it
+(although this is not useful).
