# Validate feeds

Check each named feed file against its specification and report violations with element paths.

## Steps

1. Parse the feed. Report an XML error with its line and column and stop, because element checks
   on a malformed document report noise.
2. Check the required elements for the detected feed type, and check each date's format.
3. Report one table: element path, rule, and the violating value.
