The filter for published posts doesn't validate that posts have required fields (title, description, date, slug). If a post is missing these fields, the RSS feed will have malformed items. Consider adding validation or filtering out posts without required fields.

The baseUrl in the channel link is not being escaped. While unlikely to contain special characters, for consistency and robustness: <link>${escapeXml(baseUrl)}/blog</link>
