A 'meta-grammar' is a like a grammar, except that the
RHS production can be a regular form, rather than just
a sequence of terminal or non-terminal symbols.
There exist translators for meta-grammars.
One example is the tool used to build the Python parser.
The main problem I see (due to ignorance) is how
to specify the semantic rules. For a grammar, there
the notation
$n
refers to the attributes of the n'th symbol. What do you do with
Symbol*
or
Symbol?
