Regexp separated by ':' or by ',' ??

[stackerofwheat]

In the Phishlet Format Guide for v3.0.0 there are examples of the regexp modifier being separated by both a colon and a comma. I included the examples below. Will both work or is only one correct?

COLON EXAMPLE:
'frog-[0-9]{3}:regexp'

COMMA EXAMPLE:
auth_tokens:

• domain: '.company.com'
  keys: ['.*,regexp']
  type: 'cookie'
