-5	open range (converted to a sequence from 1 to 5)
1-	open range (converted to a sequence from 1 to final number)
all	keyword representing all numbers.
odd	keyword representing odd numbers.
even	keyword representing even numbers.

The value delimiter can be either ',' or ';' and the range separator can be either '-' or ':'. Whitespace is permitted at any point in the input.

Any elements of the sequence that contain non-digit, non-whitespace, or non-separator characters or that are empty are ignored.
