Best practices
- Validate structure: Ensure tags are properly nested and closed.
- Normalize whitespace: Keep indentation consistent across files.
- Use attributes wisely: Prefer elements for complex data; attributes for metadata.
- Namespaces: Keep namespace prefixes clear and consistent.
Common pitfalls
- Unescaped special characters (
<,&) inside text nodes. - Mismatched tags or duplicate root elements.
- Incorrect character encodings for non-ASCII content.

Can I minify for production?
