-For compatibility with this program, source filenames should conform to
- the following rules :—
-
-- They should not start with a hyphen‐minus.
- This is to prevent confusion between filenames and options on the
- commandline.
-
-- They should not contain spaces, colons, percent signs, backticks,
- question marks, hashes, or backslashes.
-
-In general, filenames should be such that they do not require
- percent‐encoding in the path component of an i·r·i.
+**☡ For compatibility with this program, source filenames must not
+ contain Ascii whitespace, colons (`:`), pipes (`|`), bucks (`$`),
+ percents (`%`) or control characters, and must not begin with a
+ hyphen‐minus (`-`).**
+The former characters have the potential to conflict with make syntax,
+ and a leading hyphen‐minus is confusable for a command‐line argument.
## Parsers
⛩️📰 书社 comes with some parsers; namely :—
- **`parsers/plain.xslt`:**
- Wraps `text/plain` contents in a `<html:pre>` element.
+ Wraps `text/plain` contents in a `<html:pre class="plain">` element.
+
+- **`parsers/record-jar.xslt`:**
+ Converts `text/record-jar` contents into a
+ `<html:div class="record-jar">` of `<html:dl>` elements (one for
+ each record).
- **`parsers/tsv.xslt`:**
- Converts `text/tab-separated-values` contents into an `<html:table>`
- element.
+ Converts `text/tab-separated-values` contents into an
+ `<html:table class="tsv">` element.
-New ⛩️📰 书社 parsers should have a `<xslt:template>` element with no

on the root element of the parser to override media type support
detection.
-It is **strongly recommended** that all templates in parsers other than
- those described above be namespaced (by `@name` or `@mode`), to avoid
- conflicts between templates in multiple parsers.
+Parsers can also target specific dialects of X·M·L, in which case they
+ operate on the same basic principles as transforms (described below).
+The major distinction between X·M·L parsers and transforms is where in
+ the process the transformation happens:
+Parsers are applied *prior* to embedding (and can be used to generate
+ embeds); transforms are applied *after*.
+
+It is **strongly recommended** that auxillary templates in parsers be
+ namespaced (by `@name` or `@mode`) whenever possible, to avoid
+ conflicts between parsers.
## Embedding
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
- **`transforms/metadata.xslt`:**
Provides basic `<html:head>` metadata.
- This metadata is generated from `<html:meta>` elements with one o.
+ This metadata is generated from `<html:meta>` elements with one of
the following `@itemprop` attributes :—
- **`urn:fdc:ladys.computer:20231231:Shu1She4:title`:**
- Set `@exclude-result-prefixes` on the root `xslt:transform` element
to reduce the number of declared namespaces in the final result.
+The params `$buildtime`, `$srctime`, and `$path` are available within
+ transforms and are initialized to the current time, the time that the
+ source file was last modified, and the path of the output file within
+ $(DESTDIR).
+
## Output Wrapping
⛩️📰 书社 will wrap the final output of the transforms in appropriate
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
+ 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
