A chemical expression, reaction, equation, etc. that is set apart within the text
Conversion Note: The model for this element will allow a chemical reaction to be expressed as: just text with emphasis tags, 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.
Conversion 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 languages to this version of the Tag Set. 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. If CML is added, it will go within this <chem-struct> element.
Display Note: A chemical structure is assumed to be anchored at its position within the text.
