Wrapper element for a chemical expression, reaction, equation, etc. that is set apart from the text, and for any number, label, or caption that accompanies the chemical expression. The chemical expressions inside this element may be formally tagged as <chem-struct> elements or merely expressed as one or more display objects.
The @position attribute may be used to indicate whether this element must be anchored at its exact location within the text or whether it may float, for example, to the top of the next page, into the next column, to the end of a logical file, or within a separate window.
This element (<chem-struct-wrap>) 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, the <chem-struct-wrap> element replaces the <chem-sruct-wrapper> element, which is no longer available.

... <chem-struct-wrap> <caption> <p>Chemical equation for the oxidation of glucose into cardon dioxide and water. Unlike combustion, metabolic pathways involving glycolysis and respiration control the release of energy during oxidation, thereby permitting its storage in ATP molecules. This slow release of energy via chain reactions with multiple steps can be grouped into four stages.</p> </caption> <alternatives> <graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="pq0209587032" specific-use="internet"></graphic> <chem-struct>C<sub>6</sub>H<sub>12</sub>O<sub>6</sub> + 6 O<sub>2</sub> ⟶ 6 CO<sub>2</sub> + 6 H<sub>2</sub>O </chem-struct> </alternatives> </chem-struct-wrap> ...
