We import XML files that define logs from the previous CORE service. For an unknown reason, some of these files don't include the required namespace declarations to parse `user` values. Instead of changing the source, this change introduces a new method that forces the namespace declaration for user fields.
These fields are set using IDs from the previous CORE service. There was an incorrect assumption that these fields were integers so we were casting them as such. We have discovered that these fields are strings (e.g., `027`) so this change adjusts our types.
