on the root element of the parser to override media type support
detection.
-Parsers can also target specific dialects of X·M·L, in which case they
- operate on the same basic principles as transforms (described below).
+Even when `@书社:supported-media-types` is set, it is a requirement
+ that each parser transform any `<html:script>` elements with a
+ `@type` which matches their registered types into something else.
+Otherwise the parser will be stuck in an endless loop.
+The result tree of applying the transform to the `<html:script>`
+ element will be reparsed (in case any new `<html:script>` elements
+ were added in its subtree), and a `@书社:parsed-by` attribute will be
+ added to each toplevel element in the result.
+The value of this attribute will be the value of the `<书社:id>`
+ toplevel element in the parser.
+
+It is possible for parsers to support zero plaintext types.
+This is useful when targeting specific dialects of X·M·L; parsers in
+ this sense 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
and update them accordingly; it will signal an error if the
dependencies are recursive.
+## Output Redirection
+
+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).
+
## Transforms
Transforms are used to convert X·M·L files into their final output,
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
