Should we use Enum or String for the lists?

For example the following XML:

    <included-activities>
      <in-app-billing>no</in-app-billing>
      <gambling>no</gambling>
      <advertising>no</advertising>
      <user-generated-content>no</user-generated-content>
      <user-to-user-communications>no</user-to-user-communications>
      <account-creation>no</account-creation>
      <personal-information-collection>no</personal-information-collection>
    </included-activities>

Should we create Enum with all included activity tag options or simply pass a string?

It seems enum will be better
