[erlang-questions] `mnesia:dump_tables/1' and the schema table

[Francesco Mazzoli]

Hi,

For some reason, `mnesia:dump_tables/1' refuses to dump the schema 
table: 
https://github.com/erlang/otp/blob/maint/lib/mnesia/src/mnesia_schema.erl#L2797 
.

1) Why is this the case?
2) This is not documented, see 
http://www.erlang.org/doc/man/mnesia.html#dump_tables-1 and 
http://www.erlang.org/doc/apps/mnesia/Mnesia_chap7.html#id77600

Francesco.
