Lets assume I have the following sequence:
'[
SomeMandatorySymbol
AnotherMandatorySymbol
123
"mandatory string"
2 "a"
9 "c"
11 "f"
23 "x" ]
e.g. [(one Symbol) (one Symbol) (one Int) (one Str) ... ]
What should I insert instead ... to have valid schema for variable length interleaved ints and strings?
