+### Attributes added during parsing
+
+⛩️📰 书社 will add a few attributes to the output of the parsing step,
+  namely :⁠—
+
+- A `@书社:cksum` attribute on toplevel result elements, giving the
+    `cksum` checksum of the corresponding source file.
+
+- For the elements which result from parsing plaintext `<html:script>`
+    elements :⁠—
+
+  - A `@书社:parsed-by` attribute, giving a space‐separated list of
+      parsers which parsed the node.
+    (Generally, this will be a list of one, but it is possible for the
+      result of a parse to be another plaintext node, which may be
+      parsed by a different parser.)
+
+  - A `@书社:media-type` attribute, giving the identified media type of
+      the plaintext node.
