+//! The text content type.
+//!
+//! **Text** contains phrasing content such as attention (emphasis, strong),
+//! media (links, images), and actual text.
+//!
+//! The constructs found in text are:
+//!
+//! * Autolink
+//! * Attention
+//! * HTML (text)
+//! * Hard break escape
+//! * Code (text)
+//! * Line ending
+//! * Label start (image)
+//! * Label start (link)
+//! * [Character escape][crate::construct::character_escape]
+//! * [Character reference][crate::construct::character_reference]
