The header will be defined by the following sequence of bytes:
{ 'T','B','3','P',MAJOR_VERSION,MINOR_VERSION,PATCH_LEVEL,INTERNAL_REVISION }
The meta-object for the rest of the sequence will be determined as a little-endian encoded 32-bit number, whose meaning is defined by the Tunes project.
The registery is given in terms of names, that would be defined in the equivalent of a C include file.
In the case of a language like C that ain't got without local scoping, a common prefix like TGMORN_ (for Tunes Global Meta-Object Registry Number) would be prepended. Underscores may become minuses in other languages like Scheme. Such definitions would be automatically generated by a registry query program.
