  11 *Allowed values*: `98`, `03`, `0x`, `11`, `1y`, `14`, `1z`, `17`, `2a`,
  12 `latest`.
  13 +
  14 Specifies the version of the C++ Standard Language to build with. All the
  15 official versions of the standard since "98" are included.  It is also possible
  16 to specify using the experimental, work in progress, `latest` version. Some
  17 compilers specified intermediate versions for the experimental versions leading
  18 up to the released standard version. Those are included following the GNU
  19 nomenclature as `0x`, `1y`, `1z`, and `2a`. Depending on the compiler `latest`
  20 would map to one of those.
  21
  22 NOTE: This is an `optional` feature. Hence when not specified the compiler
  23 default behaviour is used.
  24
  25 NOTE: Please consult the toolset specific documentation for which `cxxstd`
  26 is supported.

  40 +
  41 Indicates if a non-standard dialect should be used. These usually have
  42 either/or extensions or platform specific functionality. Not specifying the
  43 dialect will default to 'iso' which will attempt to use ISO C++ Standard
  44 conformance to the best of the compiler's ability.
