 The `content` field must be the base64-encoding of a binary-serialized
 [`oracle_annoucement` object](https://github.com/discreetlogcontracts/dlcspecs/blob/master/Messaging.md#the-oracle_annoucement-type).
 
+The optional `title` tag gives observers a short human-readable title with which to display the announcement in cards, hyperlinks, etc. It _should_ be at most 100 characters of UTF8 text. Clients _should_ ignore or truncate titles longer than 100 characters. This tag must NOT be parsed as markdown or HTML.
+
+The optional `description` tag provides a human-readable summary of the real-world event which this announcement is for. The `description` should give observers context, so that they know how the real-world event in question will be reflected in the oracle's final attestation. This tag must NOT be parsed as markdown or HTML.
