-Custom C++-specific elements
-----------------------------
-
-### `<cxx-clause>` and `<cxx-section>`
-
-These automatically number clauses and sections, fill in
-table-of-contents data, and allow cross-linking. `<cxx-clause>` is for
-top-level sections, while `<cxx-section>` can be nested arbitrarily.
-The title of the section is given in a nested `<h1>` element.
-The `id` attribute is used for cross-linking.
-
-### `<cxx-titlepage>`
-
-Wraps the title page of an ISO document. The title page takes a
-`stage` attribute whose value can be `draft` or (once I implement
-them) `CD`, `DTS`, `TS`, etc.  The title page recognizes several
-nested elements that describe the document.
-
-#### `<cxx-docnum>`
-
-The D or N number for the document.
-
-#### `<time pubdate>`
-
-The publication date of the document in ISO (YYYY-MM-DD) format.
-
-#### `<cxx-revises>`
-
-The N number of the previous version of the document.
-
-#### `<cxx-editor>`
-
-A paragraph describing the editor of the document.  Use `<br>` to
-separate lines.
-
-### `<cxx-toc>`
-
-Generates a table of contents based on the `<cxx-section>` structure.
-
-### `<cxx-publish-button>`
-
-Open the document using Polymer's shadow-dom polyfill (add
-`?shadow=polyfill` to the URL) and then click this button to generate
-a standalone version of the document, that doesn't rely on any custom
-elements, scripts, or external CSS.  The result of this transformation
-is what actually gets published in the C++ committee mailings.
-
-It's tested back to IE 8 and should degrade fairly gracefully in even
-older browsers.
-
-
-### `<dl is="cxx-definition-section">`
-
-Numbers the terms in the `<dl>` with the parent `<cxx-section>`'s section
-number, and formats and links the `id`.
-
-
-### `<cxx-ednote>`
-
-An editor's note that won't appear in the final published document.
-This is formatted as a separate box on the side of the document.
-
-
-### `<cxx-email>`
-
-Must contain an email address as text, and wraps it into an
-appropriate `mailto:` link.
-
-### `<cxx-function>`
-
-Describes a C++ library function.  Several nested elements help
-describe the signatures and semantics of a function.
-
-#### `<cxx-signature>`
-
-Use one of these for each related function signature that can be
-described by a single set of attributes.
-
-#### `<cxx-requires>`, `<cxx-effects>`, `<cxx-synchronization>`, `<cxx-postconditions>`, `<cxx-returns>`, `<cxx-throws>`, `<cxx-exception-safety>`, `<cxx-remarks>`, `<cxx-error-conditions>`, and `<cxx-notes>`
-
-Each of these elements represents one attribute from [structure.specifications]p3 ([except for `<cxx-exception-safety>`](https://github.com/cplusplus/draft/issues/228)).
-
-### `<cxx-note>`
-
-Wraps non-normative text inside a paragraph.
-
-### `<cxx-ref>`
-
-Links to a section in the current document, whose `id` is given by the
-`to` attribute on the `<cxx-ref>`.  References are displayed like
-"`(1.2.3)`", unless the `insynopsis` attribute is also present, in
-which case the reference is displayed as a C++ comment, "`// 1.2.3,
-title of referenced section`".
-
-### `<table is="cxx-table">`
-
-Adds a "Table # —" prefix to the table `<caption>`.
