 Note that unlike other Markdown renderers (notably Jupyter and GitHub), lists in Quarto require an entire blank line above the list. Otherwise the list will not be rendered in list form, rather it will all appear as normal text along a single line.

+Besides the `term` / `: definition` syntax shown above, you can write a definition list as a fenced div with the `.definition-list` class containing a bullet list. Each top-level bullet is a term, and the bullets nested under it are its definitions:
+
+``` markdown
+::: {.definition-list}
+* `time`
+  - A timestamp that identifies
+    when the request was initiated.
+  - Type: string
+* `id`
+  - A unique identifier.
+:::
+```
+
+This renders as:
+
+::: {.definition-list}
+* `time`
+  - A timestamp that identifies
+    when the request was initiated.
+  - Type: string
+* `id`
+  - A unique identifier.
+:::
+
+A definition can hold several paragraphs, code blocks, or other lists, as long as they are indented under its bullet. Separate the bullets with blank lines when a definition has more than one paragraph.
+
+This is the definition list syntax of Quarto 2, which doesn't support the `: definition` syntax. Using it now lets your documents work in both versions.
+
+A `.definition-list` div must contain only the bullet list, and each term must have a nested bullet list of definitions. A div that doesn't follow this structure is rendered as an ordinary div. Any id, other classes, or attributes on the div are not kept on the definition list.
