1//! MDX JSX (text) occurs in the [text][] content type.
2//!
3//! ## Grammar
4//!
5//! MDX JSX (text) forms with the following BNF
6//! (<small>see [construct][crate::construct] for character groups</small>):
7//!
8//! ```bnf
9//! mdx_jsx_text ::= mdx_jsx
10//!
11//! ; See the `partial_mdx_jsx` construct for the BNF of that part.
12//! ```
13//!
14//! See [`mdx_jsx`][mdx_jsx] for more info.
15//!
16//! ## Tokens
17//!
18//! * [`MdxJsxTextTag`][Name::MdxJsxTextTag]
19//! * see [`mdx_jsx`][mdx_jsx] for more
