Support logging configuration

**Problem**
When working with validation, the error messages could be more descriptive.

**Suggestion**
Improve error handling and add detailed error messages.

**Context**
This would help with debugging and maintenance.

The issue names logging configuration, validation, and error handling but does not identify files, tests, or an entry point. First locate the validation and logging code, then clarify which configuration options and error-message details are required; done should include the agreed behavior and tests for it.
