+There are a few special elements in the `书社:` namespace which, if

+They are :⁠—

+- **`<书社:archive>`:**

+- **`<书社:base64-binary>`:**
+  The text nodes in the transformation result will, after removing all

+    decoded.
+
+- **`<书社:raw-text>`:**
+  A plaintext (U·T·F‐8) file will be produced from the text nodes in
