Some aspects of [Pandoc's Markdown citation syntax](#citations) are also accepted

+In the `context` output format this enables the use of [Natural Tables
+(TABLE)](http://wiki.contextgarden.net/TABLE) instead of the default
+[Extreme Tables (xtables)](http://wiki.contextgarden.net/xtables).
+Natural tables allow more fine-grained global customization but come
