+//! 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]
