- 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"

+ <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.
