A chemical expression, reaction, equation, etc., that is set apart within the text
Authoring Note: While this element contains an optional Label (of a Figure, Reference, Etc.) element, the Label (of a Figure, Reference, Etc.) element should be included only in those circumstances where a formatting override is needed; Label (of a Figure, Reference, Etc.) should NOT be used in the ordinary course of tagging.
Authoring Note: The model for this element will allow a chemical reaction to be expressed as: just text with emphasis tags, a MathML or TeX equation, a graphic, etc. Alternatively, if the reaction cannot be expressed in a simple fashion, the linking attributes may be used to point an external source such as a URI, for a more complete explanation.
Authoring Note: Accessibility elements (such as <long-desc>) should not be used with this element if they can be used as part of the containing Chemical Structure Wrapper <chem-struct-wrapper> element. Accessibility elements are allowed within this element only to handle the case in which a single <chem-struct-wrapper> wrapper element contains more than one Chemical Structure (Display) <chem-struct> within it.
Design Note: The decision was made not to add CML or other formal chemical markup language to this version of the DTD. Some equations can be marked up in MathML; others are just ASCII expressions with subscripts, superscripts, and special characters. The list class elements can be used to express the Elsevier DTD <compound-info> element.
Display Note: A chemical structure is assumed to be anchored at its position within the text.
Any combination of:
No sample is available at this time, as this element is rare in STM journal publishing, being more commonly used in STM books.
