+These include :—
-- A `@书社:cksum` attribute on toplevel result elements, giving the
- `cksum` checksum of the corresponding source file.
+- A `@书社:parsed-by` attribute, giving a space‐separated list of
+ parsers which parsed the node.

- (Generally, this will be a list of one, but it is possible for the

- - A `@书社:media-type` attribute, giving the identified media type of

+By default, ⛩📰 书社 installs files to the same location in `DESTDIR`
+ as they were placed in their `SRCDIR`.
+This behaviour can be customized by setting the `@书社:destination`
+ attribute on the root element, whose value can give a different path.
+This attribute is read after parsing, but before transformation (where
+ it is silently dropped).
## Embedding

parsers are able to generate their own embeds.

+
+- A `@书社:mtime` attribute giving the last modified time of the

## Output Wrapping
-⛩️📰 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.
-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
+Provided at least one toplevel result element belongs to the H·T·M·L
+ namespace, ⛩📰 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.
+If a toplevel result element _is_ a `<html:html>` and `<html:body>`
+ element, it will be merged with the one that ⛩📰 书社 creates.
+Consequently, wrapping the result in a `<html:body>` element can be
+ used to enable wrapping for non‐H·T·M·L content, when desired.
+
+As a part of this process, after performing the initial transform
+ ⛩📰 书社 will match in the following modes to fill in areas of the
wrapper :—
- **`书社:header`:**
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:include>` 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 :—
+The document being matched will contain the full transform result
+ prior to wrapping as well as an `<xslt:include>` element (with an
+ `@书社:id` attribute) for each transform which has a valid
+ `<书社:id>`.
+The latter elements can be matched to enable transforms to provide
+ 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"?>
