Some tokens cannot be created yet because they are more complex but eventually the creator will
deal with them. The indices are sometimes the same as internal but in most cases nicely start
at zero. When they start at another value, then there is an internal token or state that is not
user accessible. You always need to use symbolic constants as the numbers can change.
The first column is a classifier (which is experimental and categories might change when we feel
the need).

Here is a typeset table of \type {\startframed} using \type {\luatokentable\startframed}:
\luatokentable\startframed
which calls \type {\pack_framed_start_framed} where \type {\luatokentable\pack_framed_start_framed} gives:
\unprotect
\luatokentable\pack_framed_start_framed
\protect
So you can guess what generates this:
\unprotect
\luatokentable\pack_framed_start_framed_nop
\protect
And this:
\unprotect
\luatokentable\pack_framed_start_framed_yes
\protect
