# ⛩️📰 书社
<b>A make·file for X·M·L.</b>
A white·space‐separated list of media types to consider X·M·L
(default: `application/xml text/xml`).
-- **`GENERATOR`:**
- The name of the generator program (default: `⛩️📰 书社`).
-
-- **`VERSION`:**
- The current version of `GENERATOR` (default: derived from the current
+- **`THISREV`:**
+ The current version of ⛩️📰 书社 (default: derived from the current
git tag/branch/commit).
- **`SRCREV`:**
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`).
-- **`GENERATOR`:**
- The value of the `GENERATOR` variable (if present).
+- **`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).
- **`SRCTIME`:**
The time at which the source file was last modified.
-- **`VERSION`:**
- The value of the `VERSION` variable (if present).
+- **`THISREV`:**
+ The value of the `THISREV` variable (if present).
The following params are only available in transforms :—
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>`.
+
+## 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`.
