//! Constants needed to parse markdown.

//! Most of these constants are magic numbers, such as the number of markers
//! needed to parse [code (fenced)][code_fenced]

//! in a [heading (atx)][heading_atx]

//! Some constants are instead lists of things, such as the list of tag names
//! considered in the **raw** production of [HTML (flow)][html_flow]
//! ([`HTML_RAW_NAMES`][]), or the list of named character references
//! ([`CHARACTER_REFERENCES`][]).
