# ⛩️📰 书社
<b>A make·file for X·M·L.</b>
5. ⛩️📰 书社 uses the dependency tree to establish prerequisites for
each output file.
-6. ⛩️📰 书社 compiles each output file to `build/public`.
+6. ⛩️📰 书社 compiles each output file to `build/result`.
-7. ⛩️📰 书社 copies the output files to `public`.
+7. ⛩️📰 书社 symlinks most output files from `build/result` to
+ `build/public`, but it does some additional processing instead on
+ those which indicate a non‐X·M·L desired final output form.
+
+8. ⛩️📰 书社 copies the final resulting files to `public`.
You can use `make list` to list each identified source file or include
alongside its computed type and dependencies.

is an asset, in which case an `<html:object>` element is produced
instead (with the contents of the asset file provided as a base64
`data:` u·r·i).
+Embed replacements will be given a `@书社:identifier` attribute whose
+ value will match the `@xlink:href` of the embed.
Embedding takes place after parsing but before transformation, so
parsers are able to generate their own embeds.
after all necessary parsing and embedding has taken place.
⛩️📰 书社 comes with some transforms; namely :—
-- **`transforms/attributes.xslt`:**
- Applies transforms to the children of any `<书社:apply-attributes>`
- elements, and then applies the attributes of the
- `<书社:apply-attributes>` to each result child, replacing the
- element with the result.
- This is useful in combination with image embeds to apply alt‐text to
- the resulting `<html:img>`.
-
- **`transforms/asset.xslt`:**
Converts `<html:object>` elements which correspond to recognized
media types into the appropriate H·T·M·L elements, and deletes
- **`urn:fdc:ladys.computer:20231231:Shu1She4:title`:**
Provides the title of the page.
- ⛩️📰 书社 automatically encapsulates embeds so that their metadata
- does not propogate up to the embedding document.
+ ⛩️📰 书社 automatically encapsulates H·T·M·L embeds so that their
+ metadata does not propogate up to the embedding document.
To undo this behaviour, remove the `@itemscope` and `@itemtype`
attributes from the embed during the transformation phase.
- **`CKSUM`:**
The checksum of the source file (⅌ `cksum`).
+- **`IDENTIFIER`:**
+ The ⛩️📰 书社 identifier of the source file (a u·r·i beginning with
+ `about:shushe`).
+
- **`SRCREV`:**
The value of the `SRCREV` variable (if present).
Output wrapping can be entirely disabled by adding a
`@书社:disable-output-wrapping` attribute to the top‐level element in
the result tree.
+It will not be performed on outputs whose root elements are
+ `<书社:raw-text>` or `<书社:base64-binary>` (described below).
+
+## Applying Attributes
+
+The `<书社:apply-attributes>` element will apply any attributes on the
+ element to the element(s) it wraps.
+It is especially useful in combination with embeds.
+
+The `<书社:apply-attributes-to-root>` element will apply any attributes
+ on the element to the root node of the final transformation result.
+It is especially useful in combination with output wrapping.
+
+In both cases, attributes from various sources are combined with
+ white·space between them.
+Attribute application takes place after all ordinary transforms have
+ completed.
+
+Both elements ignore attributes in the `xml:` namespace, 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:` namespace 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:raw-text>`:**
+ A plaintext (U·T·F‐8) file will be produced from the text nodes in
+ the transformation result.
+
+- **`<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.
