+ installed on your computer†.
+
+† The only non‐Posix programs‡ required are those provided by `libxml2`
+ and `libxslt` (which most operating systems provide), but on Linux
+ machines the commandline utilities may need to be installed
+ separately as **`libxml2-utils`** and **`xsltproc`**.
+Additionally, not all Linux distributions bundle all necessary Posix
+ programs; on Debian (for example) you may need to separately install
+ **`sharutils`** for `uudecode` and `uuencode` and **`pax`** for
+ archiving.
+
+‡ This make·file also currently depends on non‐Posix `stat` but
+ attempts to handle both the G·N·U and B·S·D variants.
+It expects `xargs` to accept a `-0` option, which, while widely
+ supported, is not a part of the Posix standard.

### Attributes added during parsing
To undo this behaviour, remove the `@itemscope` and `@itemtype`
attributes from the embed during the transformation phase.
+- **`transforms/serialization.xslt`:**
+ Replaces `<书社:serialize-xml>` elements with the (escaped)
+ serialized X·M·L of their contents.
+ This replacement happens during the application phase, after most
+ other transformations have taken place.
+
+ If a `@with-namespaces` attribute is provided, any name·space nodes
+ on the toplevel serialized elements whose U·R·I’s correspond to the
+ definitions of the provided prefixes, as defined for the
+ `<书社:serialize-xml>` element, will be declared using name·space
+ attributes on the serialized elements.
+ Otherwise, only name·space nodes which _differ_ from the definitions
+ on the `<书社:serialize-xml>` element will be declared.
+ The string `#default` may be used to represent the default
+ name·space.
+ Multiple prefixes may be provided, separated by white·space.
+
+ When it comes to name·spaces used internally by ⛩️📰 书社, the
+ prefix used by ⛩️📰 书社 may be declared _in addition to_ the
+ prefix(es) used in the source document(s).
+ It is not possible to selectively only declare one prefix for a
+ name·space to the exclusion of others.
+
+ `<书社:raw-output>` elements may be used inside of
+ `<书社:serialize-xml>` elements to inject raw output into the
+ serialized X·M·L.

The following are recommendations on effective creation of
transforms :—
It is likely an error if two transforms have templates which match
the same element (unless the templates have different priority).

## Global Params
Output wrapping can be entirely disabled by adding a
`@书社:disable-output-wrapping` attribute to the top‐level element in
the result tree.
-This attribute will also prevent wrapping non‐H·T·M·L embeds with an
- `<html:div>`.
+It will not be performed on outputs whose root elements are
+ `<书社:archive>`, `<书社:base64-binary>`, or `<书社:raw-text>`
+ (described below).
## Applying Attributes
Attribute application takes place after all ordinary transforms have
completed.
-Both elements ignore attributes in the `xml:` namespace, except for
+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.
