⛩️📰 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: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>
+```
