A chemical expression, reaction, equation, etc. that is set apart within the text
This element accommodates chemical reactions expressed in many ways: as text with emphasis tags, subscripts, and superscripts; as a preformatted area (<preformat>), as an included graphic, etc. The linking attributes may also be used to point to an external source such as a URI.
Display Note: A chemical structure is assumed to be anchored at its position within the text.
This element (<chem-struct>) has been significantly remodeled in version 3.0 of the Tag Set. The values and/or usage in version 3.0 are not backward-compatible with that in previous versions of the Tag Set. Specifically, in prior versions the <chem-struct> element was allowed inside the <app>, <app-group>, <body>, <boxed-text>, <disp-quote>, <fig>, <glossary>, <notes>, <ref-list>, <sec>, <supplementary-material>, and <table-wrap> elements; in those places, it has been replaced by the <chem-struct-wrap> element.
Conversion Note: For users of Elsevier Tag Sets, the list class elements can be used to express the <compound-info> element inside a chemical structure.
