+- **`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>`.
