 ⛩️📰 书社 comes with some transforms; namely :⁠—
 
 - **`transforms/asset.xslt`:**
-  Converts `<html:object type="text/css">` elements into corresponding
-    `<html:link rel="stylesheet">` elements and
-    `<html:object type="text/javascript">` elements into corresponding
-    `<html:script>` elements.
-  This transform enables embedding of `text/css` and `text/javascript`
-    files, which ordinarily are considered assets (as they lack
-    associated parsers).
+  Converts `<html:object>` elements which correspond to recognized
+    media types into the appropriate H·T·M·L elements, and deletes
+    `<html:style>` elements from the body of the document and moves
+    them to the head.
 
 - **`transforms/metadata.xslt`:**
   Provides basic `<html:head>` metadata.
-  This metadata is generated from `<html:meta>` descendants of the
-    first element with an `@itemscope` attribute (recommended to just
-    be the root element).
-  Such elements can provide metadata using the following `@itemprop`

 ⛩️📰 书社 will wrap the final output of the transforms in appropriate
   `<html:html>` and `<html:body>` elements, so it is not necessary for
   transforms to do this explicitly.
-The `<html:head>` of the output will contain the result tree generated
-  by matching the root node in the `书社:metadata` mode; the provided
-  `transforms/metadata.xslt` transform uses this mode to generate basic
-  metadata, but it is possible for other transforms to add their own.
+After performing the initial transform, ⛩️📰 书社 will match the root
+  node of the result in the following modes to fill in areas of the
+  wrapper :⁠—
+
+- **`书社:header`:**
+  The result of matching in this mode is prepended into the
+    `<html:body>` of the output (before the transformation result).
+
+- **`书社:footer`:**
+  The result of matching in this mode is appended into the
+    `<html:body>` of the output (after the transformation result).
+
+- **`书社:metadata`:**
+  The result of matching in this mode is inserted into the
+    `<html:head>` of the output.
+
+In addition to being called with the transform result, each of these
+  modes will additionally be called with a `<xslt:include>` element
+  corresponding to each transform.
+If a transform has a `<书社:id>` top‐level element whose value is an
+  i·r·i, its `<xslt:import>` element will have a corresponding
+  `@书社:id` attribute.
+This mechanism can be used to allow transforms to insert content
+  without matching any elements in the result; for example, the
+  following transform adds a link to a stylesheet to the `<html:head>`
+  of every page :⁠—
+
+```xml
+<?xml version="1.0"?>
+<transform
+  xmlns="http://www.w3.org/1999/XSL/Transform"
+  xmlns:html="http://www.w3.org/1999/xhtml"
+  xmlns:xslt="http://www.w3.org/1999/XSL/Transform"
+  xmlns:书社="urn:fdc:ladys.computer:20231231:Shu1She4"
+  exclude-result-prefixes="书社"
+  version="1.0"
+>
+  <书社:id>example:add-stylesheet-links.xslt</书社:id>
+  <template match="xslt:include[@书社:id='example:add-stylesheet-links.xslt']" mode="书社:metadata">
+    <html:link rel="stylesheet" type="text/css" href="/style.css"/>
+  </template>
+</transform>
+```
+
+Output wrapping can be entirely disabled by adding a
+  `@书社:disable-output-wrapping` attribute to the top‐level element in
+  the result tree.
