Portable prose
Headings, paragraphs, emphasis, quotes, lists, links, images, and code cover most durable documentation.
Markdown profile
CommonMark: the carefully specified core.
Use MDLoom's CommonMark 0.31.2 target when a small, specified syntax surface matters more than tables, task lists, or product-specific extras.
commonmark-0.31.2
The editor stores the selected profile ID and performs a source-preserving dry-run before a profile switch. Full historical renderer replay is a separate release gate.
Good fit
Choose CommonMark for a stable, portable baseline
Testable behavior
The profile targets the named specification and has repository fixtures for representative behavior rather than relying on a vague “standard Markdown” label.
Clear boundaries
Tables, task lists, strikethrough, math, diagrams, alerts, and footnotes are not silently added.
Safe rendering
Raw HTML remains governed by MDLoom's explicit policy and sanitizer; a syntax standard is not a security boundary.
Example
Readable before and after rendering
