[microprofile-dev] 2 ConfigSources same ordinal

[Rebecca Searls <rsearls@xxxxxxxxxx>]

When 2 ConfigSources have the same ordinal value,
what is the rule for an implementation's setting order
in the Config's ConfigSource list.

Example:
  BobsIncredibleLibConfigSource ordinal = 110 returns property prodName=BobsIncredibleLib
  User includes BobsIncredibleLibConfigSource in his app but also provides
    UsersCoolAppConfigSource ordinal = 110 and property prodName=UsersCoolApp

In what order are these ConfigSources set in Config's list?
Is there a rule that provides order consistency?
