+  `<书社:archive>`, `<书社:base64-binary>`, or `<书社:raw-text>`
+  (described below).
+
+## Applying Attributes
+
+The `<书社:apply-attributes>` element will apply any attributes on the
+  element to the element(s) it wraps.
+It is especially useful in combination with embeds.
+
+The `<书社:apply-attributes-to-root>` element will apply any attributes
+  on the element to the root node of the final transformation result.
+It is especially useful in combination with output wrapping.
+
+In both cases, attributes from various sources are combined with
+  white·space between them.
+Attribute application takes place after all ordinary transforms have
+  completed.
+
+Both elements ignore attributes in the `xml:` name·space, except for
+  `@xml:lang`, which ignores all but the first definition (including
+  any already present on the root element).
+On H·T·M·L and S·V·G elements, `@lang` has the same behaviour as
+  `@xml:lang`.
+
+## Other Kinds of Output
+
+There are a few special elements in the `书社:` name·space which, if
+  they appear as the toplevel element in a transformation result, cause
+  ⛩️📰 书社 to produce something other than an X·M·L file.
+They are :⁠—
+
+- **`<书社:archive>`:**
+  Each child element with a `@书社:archived-as` attribute will be
+    archived as a separate file in a resulting tarball (this attribute
+    gives the file name).
+  These elements will be processed the same as the root elements of any
+    other file (e·g, they will be wrapped; they can themselves specify
+    non X·M·L output types, ⁊·c).
+  Other child elements will be ignored.
+
+- **`<书社:base64-binary>`:**
+  The text nodes in the transformation result will, after removing all
+    Ascii whitespace, be treated as a Base·64 string, which is then
+    decoded.
+
+- **`<书社:raw-text>`:**
+  A plaintext (U·T·F‐8) file will be produced from the text nodes in
+    the transformation result.
