A phrase within an \elementref{indexmark} Attributes for \elementref{indexphrase}. a flattened form of the phrase for generating an \attr{ID}. Content model for \elementref{indexphrase}. A see-also phrase within an \elementref{indexmark} Attributes for \elementref{indexsee}. a flattened form of the phrase for generating an \attr{ID}. a name for the see phrase, such as "see also". Content model for \elementref{indexsee}. A phrase being clarified within an \elementref{glossaryentry} Attributes for \elementref{glossaryphrase}. The kind of \elementref{glossary} this mark belongs to. a flattened form of the phrase for generating an \attr{ID}. a keyword naming the format of this phrase (to match \attr{show} in \elementref{glossaryref}). Content model for \elementref{glossaryphrase}. A definition within an \elementref{glossaryentry} Attributes for \elementref{glossarydefinition}. a flattened form of the definition for generating an \attr{ID}.

A \elementref{inline-para} child should have attribute \attr{class} being one of \texttt{ltx_page_navbar}, \texttt{ltx_page_header} or \texttt{ltx_page_footer} and its contents will be used to create those components of webpages. Lacking those, a \elementref{TOC} requests a table of contents in the navigation bar. Page headers and footers will be synthesized from Links from the current page or document to related ones; these are represented by \elementref{ref} elements with \attr{rel} being up, down, previous, next, and so forth. top-level elements, presumably block-level,
