/// The symbolic names are, where applicable, the name of the symbol without

/// Examples: [$exclamation], [$pipe], [$dollar] and [$grave].
/// For less common symbols, a selection of common names are used.

/// For parenthetical markers, there is both a short name, [$lparen]/[$rparen],
/// and a long name, [$open_paren]/ [$close_paren].
///
/// For common HTML entities, the entity names are also useable as symbolic
