Explanation

preamble-eip makes sure the eip front matter (or preamble) field is a non-negative integer.

Each proposal is identified with a number. The eip field holds that number.

Before an EIP Editor assigns a number, it is acceptable to leave this field as eip: <to be assigned> or omit it entirely.
